The ends of the linear chromosomes of eukaryotes cannot be replicated by DNA polymerase. This problem is overcome through the use of telomerase, an enzyme implicated in aging and cell lifespan. Telomerase contains a noncoding RNA that acts as a moving template to add a repetitive DNA sequence at the chromosome tip, preventing the loss of essential DNA. In mammals, the ends of the chromosomes fold back to form a circular structure called a T‑loop.
Select the answers that correctly describe telomeres and the actions of telomerase.
a. Telomerase is a specialized reverse transcriptase and its presence within eukaryotic cells indicates that an early eukaryote was infected by a retrovirus.
b. Inappropriate activation of telomerase can result in cellular immortality, one of the cellular changes implicated in the development of cancer.
c. Telomerase activity is turned off in most human cells, causing the telomeres to gradually shorten as the individual ages.
d. The T-loop protects the chromosome ends from degradation by nucleases and double strand break repair enzymes.
e. Telomerase activity results in a telomere that is completely double-stranded with no single stranded region that would be susceptible to nucleases.
Answer:
B,C, D
Explanation:
Telemerase is a reverse transcriptase enzyme, which adds repetitive nucleotide sequences to the telomere ends of chromosomes.
This enable the telomere to protect the end of chromosomes from degenerating, and also prevent it from fusing with other adjacent chromosomes. Telomere shelved the gene ahead of it on the chromosomes from been truncated as its shorten with each division, It is in turn protected by protein shelterin
With each cell division, the shortened telomere length is replenished by the telomerase enzyme. Therefore, the telomerase maintains the stability of the telomeres.
Consequently the turning off of these enzymes shorten ages, in most human cells because, the telomere length is shortened , and cells failed to undergo cell division which leads to death of cells. Ageing. if this enzyme is over activated, cells undergo uninterrupted division,and multiplication which may lead to tumor.
Telomerase is a specialized enzyme that fills the gap left by DNA polymerase in the replication of the ends of chromosomes, known as telomeres. Its activity can influence processes related to aging and cancer development. The 'T-loop' at the end of chromosomes serves a protective function.
Explanation:The ends of eukaryotic chromosomes, known as telomeres, cannot be replicated by the DNA polymerase enzyme that is crucial in DNA replication. This gap is filled by a specialized enzyme called telomerase. This enzyme has an inbuilt RNA sequence that it uses as a movable template to append a recurring sequence that is DNA to the ends of chromosomes. This helps prevent significant DNA loss.
A few points help define telomeres and telomerase activity:
Telomerase is an exceptional reverse transcriptase. Suggesting that an early eukaryote was infected with a retrovirus is speculative.Uncontrolled activation of telomerase can result in cellular immortality, which is associated with the development of cancer.The activity of telomerase is usually switched off in most human cells, causing gradual shortening of telomeres with aging.The T-loop provides protection to the chromosome ends against disintegration by nucleases or double strand break repair enzymes.Telomerase activity results in a complete double-stranded telomere with no single stranded regions susceptible to degradation by nucleases.Learn more about Telomerase and Telomeres here:https://brainly.com/question/34616854

A woman has a condition where all of her gametes undergo nondisjunction of chromosome 21 in meiosis II, but meiosis I proceeds normally. She mates with a man who produces all normal gametes. What is the probability that the fertilized egg will develop into a child with Down syndrome (trisomy 21)
Answer:
1/4.
Explanation:
If the nondisjunction occurs in meiosis II, 4 gametes are formed in which types of gametes are 3. Out of the 4 gametes, 2 are normal, 2 will have aneuploidy as shown in the diagram attached. Out of the 2 aneuploid gametes, one will have 2 haploid chromosomes while another one will not have any chromosome at all.
Now when this female will mate with a man who has produced normal gametes, each of the gamete produced by this female will have the probability to receive 1 haploid gamete from the male. After fusion/fertilization, total 4 zygotes which are of 3 types may form. One of the zygotes will have 3 chromosomes i.e. will have trisomy (which will develop into Down's syndrome), one of them will have 1 chromosome i.e. will have monosomy while 2 zygotes will be normal i.e. will be diploid.
So, the probability of a child being born with Down's syndrome will be 1/4.
Why do you believe many cancers go unrecognized until after the formation of tumors and/or the person becomes
Answer:
Explanation:
Some cancers go unrecognised because they tend not to grow in a steady, linear order. These tumors can remain dormant for long periods of time unless triggered by a promoter agent that will promote its growth followed by a period of rapid and fast growth, such as occurs after angiogenesis is initiated. Thus, equipment that will be extremely sensitive to the processes that these cells before they metastasize has to be developed to detect their presence. Some available equipments detect their actions through the substances they shed into the bloodstream but these cells would have begun metastasis by this period.
Cancers often grow slowly and do not cause symptoms in the early stages, which makes them difficult to detect. Additionally, they can develop in parts of the body that aren't easily observable, leading to further delays in diagnosis.
Explanation:Many cancers go unrecognized until after the formation of tumours and/or the person becomes symptomatic because these diseases often develop slowly and may not cause symptoms in their early stages. The body doesn't always recognize cancerous cells because they are similar to normal body cells.
As a result, they don't cause an immunological reaction. Furthermore, tumours can grow unnoticed in areas of the body that are not easily observed, like the lungs or pancreas. This lack of immediately recognizable symptoms can lead to a delay in diagnosis.

Which two systems most directly interact in the fuzzy millipede's defense against ants?
Two systems most directly interact in the fuzzy millipede's defense against ants are :
muscular and integumentary
Explanation:
The fuzzy millipede, Polyxenus fasciculatus, is found in Texas and is preyed upon by most species of ants. Most millipedes defend themselves with a variety of chemicals secreted from pores along the body, although the tiny bristle millipedes are covered with tufts of detachable bristles. Due to their lack of speed and their inability to bite or sting, millipedes' primary defence mechanism is to curl into a tight coil – protecting their delicate legs inside an armoured exoskeleton.Reproduction in most species is carried out by modified male legs called gonopods, which transfer packets of sperm to females.Millipedes overwinter, so they may hide in cracks or crevices throughout the whole winter and emerge in the spring.These insects live in dark, damp places and feed on decaying plant life, sometimes damaging crops. But they can serve a good purpose too.To protect itself against the ants, it ejects fibers from a tuft located at the tail end of its body. When an ant attacks, the millipede flexes its back end toward the ant and wipes the tufts against it.

Consider the following experiment: True-breeding tall pea plants are cut short before being pollinated to determine if there is an effect on the offspring. Which explanation for trait inheritance is this testing?
This experiment is testing the principle of trait inheritance known as Mendelian inheritance. It aims to understand if cutting short the true-breeding tall pea plants before pollination affects the traits inherited by the offspring.
Explanation:This experiment is testing the principle of trait inheritance known as Mendelian inheritance. Mendelian inheritance refers to the idea that traits are determined by discrete units called genes, which are passed from parents to offspring. By cutting short the true-breeding tall pea plants before pollination, the experimenter is investigating if this has an effect on the traits inherited by the offspring. This allows for the examination of whether the trait is dominant or recessive based on the appearance of the offspring.
The presence of a beard on some goats is determined by an autosomal gene that is dominant in males and recessive in females. Heterozygous males are bearded, while heterozygous females are beardless. What type of inheritance is exhibited by this trait?
Answer:
Explanation:
Some autosomal genes may affect the phenotypes of individuals of one sex more than individuals of the other but they play no part in the development of being a male or being a female. this type of gene is thus a sex influenced autosomal gene. The type of inheritance exhibited by this trait in the male goat follows the autosomal dominant pattern of inheritance meaning the for the trait to be expressed, it has to be the dominant allele form on the X chromosome. In the females, this trait follows the autosomal recessive pattern of inheritance such that for a female goat to be bearded, the trait must be inherited as a homozygous recessive trait, while an heterozygous or a homozygous dominant female will be beardless.
The presence of a beard on some goats is determined by an autosomal gene that is dominant in males and recessive in females, exhibiting autosomal inheritance.
Explanation:This trait exhibits autosomal inheritance. The presence of the beard trait is determined by a gene located on an autosomal chromosome, not on the sex chromosomes. It is dominant in males, which means that even if they have only one copy of the gene, they will exhibit the trait. In females, the gene is recessive, so they must have two copies of the gene to have the trait.

Half of the gametes produced are wild-type, whereas half are mutated. Gametes are produced with extra chromosomes. Homologous chromosomes fail to separate. Gametes are produced with missing chromosomes.
Answer:
Gametes are produced with extra chromosomes. Gametes are produced with missing chromosomes.Explanation:
Non-disjunction is a genetic phenomenon that results in a failure in the segregation of sister chromatids. Non-disjunction can be classified as first or second division, however both result in genetic anomalies, because both cause excessive gamete production, or failure in gamete production, in addition to causing cells to be created with fewer chromosomes than they should It has.
For this reason, we can consider that the correct answer to your question is:
Gametes are produced with extra chromosomes. Gametes are produced with missing chromosomes.The statements "gametes are produced with extra chromosomes" and "gametes are produced with missing chromosomes" are TRUE.
Meiosis is a cell division by which a parent cell divides twice and duplicates its genetic material to produce four daughter cells (gametes) having half of the genetic material.These successive rounds of cell division are called Meiosis I and Meiosis II.Non-disjunction refers to either the faulty separation of either homo-logous chromosomes or sister chromatids during Meiosis I or Meiosis II.In conclusion, the statements "gametes are produced with extra chromosomes" and "gametes are produced with missing chromosomes" are TRUE.

Energy from the sun that enters the Earth system does not leave.
Final answer:
The statement is False. Energy from the sun that enters the Earth system does leave.
Explanation:
The statement is False. Energy from the sun that enters the Earth system does leave. While the Earth system as a whole is a closed system with virtually no mass exchanged between the Earth system and the rest of the universe, energy in the form of solar radiation passes from the Sun to the Earth and Earth emits radiation back out to space. This means that energy does cross the Earth's system boundary, making it a closed system.

Answer:
The correct answer is: 1,4' linked polymers of D-glucose which differ in the stereochemistry of this linkage.
Explanation:
Cellulose and amylose are both polysaccharides and polymers of glucose (which means that they are composed of glucose molecules). While cellulose is mostly found on the cell wall of plants and algae, amylose (along with amylopectin) form the main carbohydrate in humans' diets: starch.
While the glucose molecules in amylose are linked by α(1-4) glycosidic bonds, the glucose molecules in cellulose have β(1-4) glycosidic bonds. This particularity is what makes amylose and cellulose compounds differ from one another.
Answer:
1,4' linked polymers of D-glucose which differ in the stereochemistry of this linkage
Explanation:
Cellulose and amylose are polymers of glucose. Amylose's monomeric units are linked by alpha α-1,-4-glycosidic bonds and cellulose monomeric units are joined by β 1-4 glycosidic bonds. These two substances are carbonhydrates; polysaccharides in particular: polymeric carbohydrates composed of monosaccharide units linked toghether by glcosidic bonds.

What landslide will produce the highest amount of kinetic energy for an object of constant mass moving down it
Answer:
Landslide will produce the highest amount of kinetic energy if it moves with high speed and with a large mass.
Explanation:
Kinetic energy is type of energy which depends on the speed and mass of the body. Kinetic energy has direct relation with mass and speed of the body. If speed and mass of an object is higher, maximum kinetic energy will be produced in the object while the object has lower kinetic energy if it has lower speed and less mass. So this phenomenon is also apply on the kinetic energy of landslide. If mass and speed of the landslide is higher, its kinetic energy is also higher.
Enzymes work in biological systems by _________. View Available Hint(s) Enzymes work in biological systems by _________. decreasing the equilibrium constant lowering the activation energy of a reaction increasing the equilibrium constant increasing the activation energy of a reaction g
The complete sentence should be, 'Enzymes work in biological systems by lowering the activation energy of a reaction.'
This is essential because the activation energy is the minimum amount of energy needed for a chemical reaction to occur. By reducing this energy threshold, enzymes make it easier for reactions to happen, thus speeding up biochemical processes.For example, without enzymes, many metabolic reactions in our bodies would proceed too slowly to sustain life. Enzymes achieve this by binding to the reactants and stabilizing the transition state, which ultimately reduces the energy needed to reach it.

As an aspiring undergraduate researcher, you want to identify the gene responsible for bacterial virulence of your favorite pathogenic microbe. After subjecting your favorite microbe to random mutagenesis (i.e. forward genetics), you identify a mutant strain that has completely lost its virulence properties. Partial sequencing of your favorite pathogen’s genome reveals a mutation in the DNA sequence encoding gene X. You are excited, and rush to write a paper proclaiming your exciting result that gene X is responsible for the virulence of your favorite pathogen, which you hope to publish in a top journal. However, your cautious lab-mate encourages you to not to be too hasty, and convinces you to generate and test the exact same mutation in gene X by directed mutagenesis (i.e. reverse genetics). Much to your horror, when you test the effects of the directed gene X mutation in your animal model, the strain containing the directed mutation in gene X was fully virulent relative to the wild type strain of your favorite pathogen. Based on these data alone, what is the most likely reason that the strain generated by random mutagenesis had fully lost virulence, while the same mutation introduced by directed mutagenesis resulted in a strain of your favorite pathogen that was fully virulent?
Answer:
When directed mutagenesis which is also called reverse genetics is used, only a single mutation per genome is introduced. In contrast, the number of mutations per genome introduced by random mutagenesis is usually difficult to control. It is likely that the strain you obtained with a mutation in gene X after random mutagenesis contained an additional mutation or perhaps multiple mutations which ultimately was/were responsible for loss of virulence in your favorite pathogen.
