What is the end result of using a technique known as polymerase chain reaction
is it B,C, OR D???
Answers
The answer is C; Many copies of a DNA Fragment
The specific DNA sequence has been doubled. This cycle of Denature-Anneal-Extend is repeated, usually about 35 times, by using a thermocycler over 2-3 hours (the "chain reaction" of PCR). This produces 34,359,738,368 copies of DNA (That's 2^35)!
PCR is a technique used which is used to amplify DNA so, many copies of a DNA fragment will get as a end result of using PCR.
What is DNA?DNA stands for deoxyribose nucleic acid.It is a self-replicating substance that makes up the majority of chromosomes in practically all living creatures. It carries genetic information of living beings.What is PCR polymerase chain reaction?Kary B. Mullis, an American scientist, invented PCR in 1983.The polymerase chain reaction (PCR) is a laboratory technique used for rapidly amplifying millions to billions of copies of a single DNA region.PCR entails selecting a portion of the genome to be amplified using short synthetic DNA fragments called primers, followed by several rounds of DNA synthesis to amplify that segment.Amplification is accomplished by a three-step process:-Denaturation is the process of heating double-stranded DNA templates to separate the strands at 95°C.Annealing is the process of short DNA molecules called primers binding to flanking regions of target DNA at 55°C.Extension is the process of DNA polymerase extending the 3′ end of each primer along the template strands at 72°C.These processes are performed 25–35 times to make precise copies of the target DNA exponentially.
Hence, the correct option is D.

Two spotted leopards produce a litter of four cubs. Three of the cubs are spotted and one is solid black. The black coat is probably what type of trait? *
Answers
Two spotted leopards produce a litter of four cubs. Three of the cubs are spotted and one is solid black. The black coat is Recessive Trait
Explanation:
A recessive trait is a trait that have been expressed when an organism has two recessive alleles or two forms of a gene.
Traits are called the physical/non-physical characteristics of a organisms that can or cannot be observed.
Physical characteristics like hair, eye color can be observed while other characteristics like the shape of blood cells cannot be observed.
It is important to note that if the trait is dominant, one of the parents will have the trait. Dominant traits does not skip a generation. In case the trait is recessive, neither of the parent will have the trait .Recessive trait can skip a generation
So we can say that in the case mentioned in the question
Two spotted leopards produce a litter of four cubs. Three of the cubs are spotted and one is solid black. The black coat is Recessive Trait
Final answer:
In a litter of four cubs where three are spotted and one is solid black, the solid black coat is likely a recessive trait, since the spotted pattern is exhibited by the majority and is thus the dominant trait.
Explanation:
The question addresses a scenario where two spotted leopards produce a litter of four cubs, three of which are spotted, and one is solid black. Since the majority of the cubs are spotted, this suggests that the spotted pattern is the dominant trait. The solid black coat in one cub is therefore likely to be a recessive trait. In genetics, a dominant trait is one that is expressed in the phenotype even if only one copy of the allele for that trait is present (heterozygous). On the other hand, a recessive trait requires two copies of the allele (homozygous recessive) to be expressed.
Given the context, and consistent with information about cat coat genetics, the solid black color exhibited by the single cub can follow principles of incomplete dominance, co-dominance, or be influenced by multiple genes or loci, which is a more complex topic involving epistatic interactions. The most straightforward answer is that the black coat is a recessive trait when considering the simple Mendelian inheritance patterns observed in the litter.

Some people have one sickle cell gene and one normal gene. They have few defective cells and no symptoms because the sickle cell gene is recessive. How does the human system of reproduction result in people getting one copy of a sickle cell gene and one copy of a normal gene? Describe the process.
Answers
Answer:
Explanation:During fertilization the embryo receives half of its genetic information from both parents. If one parent is a carrier or sickle cell their genes would be Aa little a being the recessive gene. When mixed with the other parents gene who does not have sickle cell their genes would be AA. When you make a pun net square the results would be AA,AA,Aa,and Aa. Therefore the offspring would have a 50% chance of being a carrier of sickle cell but not having the actual disease
DNA codes for _______ which determines ________
(a) proteins, peptide bonds
(b) mRNA, tRNA
(c) mRNA, ribosome
(d) protein s, traits
Answers
DNA carries genetic information in nucleotidic sequences. This information is translated into proteins that codes for traits. Option D. Proteins - Traits.
What DNA codes for?DNA molecules carry genetic information stored in their nucleotidic sequences. This molecule has information about the whole organism and its functions.
Through protein synthesis, this information is first transcripted into mRNA molecule and then translated into proteins.
mRNA is in charge of taking only sequences that code for a single protein from the nucleus to the cytoplasm, where rRNA and tRNA will build the protein.
What are proteins and what is their function?
Proteins are complex macromolecules formed by a sequence of amino acids. They carry out several functions in the organisms.
They are in charge of most cellular activities and are necessary for the structure, function, and regulation of tissues and organs.
Proteins are in charge of determining traits or features that will be expressed by the individual through its development.
The correct option is D. DNA codes for _proteins_ which determines _traits_.

Final answer:
DNA codes for proteins which in turn determine traits, with the sequence of amino acids in a protein being critical to its function. The process involves transcription and translation with mRNA and tRNA playing key roles.
Explanation:
DNA codes for proteins which determines traits. The process begins with transcription, where DNA's nucleotide sequence is copied into messenger RNA (mRNA). This mRNA then provides the code for the sequence of amino acids in a protein during translation. Proteins are comprised of long chains of amino acids linked together by peptide bonds. The specific sequence of amino acids in a protein dictates its structure and function. Transfer RNA (tRNA) carries amino acids to the ribosome, where they are added to the growing protein chain as dictated by the mRNA sequence.
The correct answer to the question is therefore (d) proteins, traits. Proteins are responsible for carrying out a vast array of functions in cells and organisms, and the traits of an organism can be influenced by the types and functions of the proteins produced as a result of gene expression.

To determine which baby belongs to which parents in the hospital mix-up scenario, DNA fingerprints of the babies and their parents are compared to find genetic markers that confirm biological relationships. The child must share DNA markers with both parents, and the DNA analysis is used to match these genetic profiles.
Explanation:The question revolves around a scenario where three children were delivered at the same time in a hospital, and due to an emergency, their identities got mixed up. To determine which baby belongs to which parents, DNA profiles of the babies and their parents were compared to establish biological relationships based on genetic markers. By examining the DNA fingerprints of the babies and comparing them to those of the parents, the child's parents can be ascertained. The child must share genetic markers with its parents, as children inherit half of their DNA from the mother and half from the father. During a DNA analysis, specific regions of the DNA are analyzed to detect similarities that are unique to family members.
When dealing with paternity or maternity testing, a match in these genetic markers must be found between the child and the alleged parents to confirm a biological relationship. Modern forensic science often uses this approach to resolve cases of uncertain paternity or identify individuals in scenarios like the hospital mix-up described. DNA analysis is a powerful tool in maternity and paternity testing, used not only for medical and legal cases but also for research purposes.
