during transcription, is the original sequence maintained in the new strands? explain why or why not

Answers

Answer 1

During transcription, RNA polymerase synthesizes RNA complementary to DNA, maintaining sequence with modifications (e.g., T to U substitution).

1. During transcription, the original sequence of DNA is maintained in the newly synthesized RNA strands with certain modifications:

 

2. RNA polymerase binds to the DNA template and synthesizes a complementary RNA strand, following the rules of base pairing (A-U, G-C).

 

3. While the overall sequence is maintained, there are some differences:

 

4. Thymine (T) in DNA is replaced by uracil (U) in RNA.

 

5. Transcription may not cover the entire DNA sequence; only specific regions (genes) are transcribed into RNA.

 

6. Additionally, RNA processing, such as splicing and post-transcriptional modifications, can alter the final RNA sequence.

 

7. Despite these modifications, the essential information encoded in the DNA, such as the sequence of amino acids in a protein, is preserved in the newly synthesized RNA.

 

8. Therefore, while the exact nucleotide sequence is not identical, the fundamental genetic information is conserved throughout transcription.

Explanation:

In which zone can rooted plants be expected to be found attached to the seafloor? What is the name of this zone, and why are plants found there?

Answers

Hello!

The answer you're looking for is the Benthic zone:

The Benthic zone is the region at the lowest level on an ocean or lake, including the seabed. In this zone is where plants can attach themselves to the ocean floor if the water is shallow enough for the sunlight to reach them. Some plants that can be found in the Benthic zone include:

-Eel Grass
-Mangroves
-Turtle Grass
-Cattails

Answer:

Just adding a bit on what the other person said.

Plants that are attached to the ocean surface live in the benthic zone. These plants are also found in the epipelagic zone which maxes at 200m. Plants and life need warmth, oxygen, and sunlight. At these depths, all of these are available to ocean life.

Are primitive traits typical of broader or smaller clades?

Answers

Final answer:

Primitive traits are typical of broader clades as they are inherited from a distant ancestor and are shared among a large group of organisms, whereas derived traits are characteristic of smaller clades and indicate more recent evolutionary changes.

Explanation:

Primitive traits, also known as plesiomorphic traits, are typical of broader clades because these traits were present in distant ancestors. These traits persist over large groups of organisms that descend from a common ancestor. For instance, all mammals possess body hair because they share a common ancestor that exhibited this feature, making it a primitive trait within the clade of mammals. In contrast, derived traits, or apomorphic traits, are indicative of smaller clades as they represent changes that occurred after the clade diverged from other lineages. For example, the trait of walking on two legs is considered a derived trait in humans as it developed after our lineage split from other primates.

It is important to recognize that the classification of a trait as primitive or derived is relative and can vary depending on the taxa being compared. Additionally, when a lineage splits into two, it is common for one to retain more of the ancestral traits, while the other develops more derived traits. Understanding these traits helps us reconstruct evolutionary relationships and determine how closely related different species are within the clades they belong to.

What happens to allow your brain cells to take a different shape and function compared to your arm cell?

Answers

brain cells change shape when cognitive deterioration happens and when it happens in the arm the cells have been strained

Gene expression allows one cell such as brain cell to take a different shape and function compared to the other cell such as arm cell.

What is Gene expression?

Gene expression is the process which involves the transfer of information from a gene that is used in the synthesis of a functional gene product enables the production of end products, such as protein or non-coding RNA, which ultimately affect the phenotype of an individual, as the final effect.

Gene expression depends upon several factors such as, genetic makeup, exposure to harmful substances, environmental influences, and age of the organism, all can affect gene expressivity and hence the phenotype of the organism.

In gene expression, genes which are inactive are silent or unavailable for the protein development in cells. Because of this reason, the cells which carry the same instructions becomes a brain cell and another a skin cell.

A.strong winds form many minerals

B.there is little leaching

C.desert plants do not need minerals

D.few animals live there

Answers

The upper layer of desert soil is rich in minerals because there is little leaching. The correct option is B.

What is leaching?

Leaching is a mass transfer process that occurs when a substance is extracted from a solid material that has come into contact with a liquid.

The normal mechanism by which water-soluble compounds from soil or waste are washed out is leaching.

In geology, leaching is the loss of soluble substances and colloids from the top layer of soil due to percolating precipitation. Materials that are lost are carried downward and typically redeposited in a lower layer.

As a result of this transport, the top layer is porous and open, and the bottom layer is dense and compact.

Because there is little leaching, the upper layer of desert soil is rich in minerals.

Thus, the correct option is B.

why did coal never form in australia

Coal formed on Earth when Australia was near the south pole. so thats Why coal never formed in Australia


Hope This Helps tho if it dosnt message me 

In the period when the lush ancient forests exited on Earth, the ones that provided the material for the formation of the coal that we use nowadays, Australia did not provide the right conditions for the existence of these forests.

The problem was that Australia was located very close to the South Pole in that period. Because of its location, Australia was colder and drier than most of the landmass on the Earth. By having less precipitation, and colder climate, Australia was not suitable for the tropical rainforests of that period, thus it did not had the material from which the coal formed latter on in the geological time scale.

Answers

The stimulus in the situation is the cold air, this is what incites Dina to return to her house to put a coat on.
The sensory receptors are thermoreceptors, part of the exteroceptors located in the skin (exteroceptive sensitivity).
The response to the stimulus was elaborated by the somatic nervous system (which controls voluntary movements), and it was putting a coat to cover herself from the cold air, by returning at home getting it.

Sample Response:

The stimulus is the temperature of the air. Sensory receptors in the skin send signals to the brain that the temperature is cold. Motor neurons stimulate muscle cells so that Dina can move to put on her coat.

The answer in the first line is "Base-pairing rule" while in the second line is "DNA"

A chromosome unfolding enhances transportation by making DNA segments accessible for transcription. Hence, the correct option is option 1.

When a chromosome unfolds itself, the process enhances transportation by allowing specific segments of DNA to become accessible for transcription. The nucleosomes, which are complex structures of DNA and protein, can slide down the DNA to open up chromosomal regions. This opening of the chromatin structure is vital for the transcriptional machinery, such as RNA polymerase, to initiate the transcription of DNA into RNA. Hence, accessibility is significantly increased as the unfolded DNA provides an opportunity for transcription factors and RNA polymerase to bind to the exposed DNA sequences and carry out the transcription process.

Accessible, transcriptionally active regions of DNA are known as euchromatin, while DNA packaged so that it is inaccessible to regulatory protein binding is known as heterochromatin. Essentially, chromatin dynamics—such as the opening and closing of nucleosomes—allow DNA to be transcribed, move histones to open or close a chromosomal region, and are temporary changes that contribute to gene regulation.

what are the different compelments of cellular respiration

Answers

Answer:

Explanation: Cellular respiration is a multi-step process that cells use to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and release waste products. It involves three main stages

Glycolysis: Glucose → 2 Pyruvate + 2 ATP + 2 NADH

Citric Acid Cycle: 2 Pyruvate → 2 Acetyl-CoA → 4 CO2 + 6 NADH + 2 FADH2 + 2 ATP

Oxidative Phosphorylation: NADH + FADH2 → ETC → Proton Gradient → ATP Synthase → ATP (approximately 34 ATP)

Overall, cellular respiration produces up to 38 ATP molecules from one molecule of glucose (2 from glycolysis, 2 from the Krebs cycle, and about 34 from oxidative phosphorylation), although the actual yield can be slightly lower due to varying efficiencies and conditions within the cell

Analyze how twin studies help to differentiate the effects of genetic and environmental influences

Answers

Hello!

Twins share nearly the entirety of their DNA. This is very important for scientists because any differences between them would be caused by environmental influences. 

Studying twins can help elucidate whether a particular condition is caused by genetic or environmental causes. In technical terms, this is called the estimation of the genetic and environmental contribution to the phenotype

Twin and adoption studies shed light on the relative influence of genetics and environment by examining the similarities between identical twins raised apart and between adopted children and their biological or adoptive families.

Twin studies are a cornerstone of quantitative genetics, which analyze degrees of similarity between individuals to infer the respective roles of genetic and environmental factors. Identical twins separated at birth and raised in different environments present a unique opportunity to isolate the effects of their genetic makeup from environmental influences, since they share identical genes but not the same environment.

An adoption study further aids in understanding nature vs. nurture, where researchers look for similarities between adopted children and their biological versus adoptive parents. A closer resemblance to biological parents suggests genetic influences, while greater similarity to adoptive parents indicates environmental effects.

Beyond twins and adopted individuals, family studies, including extended family, siblings, and half-siblings, expand our knowledge of genetic and environmental contributions to traits and behavior.

The correct answer is all of these.

Matter and energy on Earth are never destroyed or created out of nothing, but just transferred or converted to another form.
 The inorganic matter is transferred to the living things from the physical environment by many biological processes like photosynthesis ( CO2), nitrogen fixation, absorption of the minerals by plant roots and many more.
Matter can then be transferred between different organisms through the food chain.
Eventually, the matter will return to the physical environment when organisms decompose and the cycle will start again.
