When mitosis occurs, the DNA inside the cell's nucleus must replicate. The new cell that is formed has an identical copy of its

parent cell's DNA. That means it has the same information coded in its genes. During DNA replication, how is an accurate new copy of DNA formed?
DNA polymerases add nucleotides to the exposed base pairs according to base-pairing rules.

During DNA replication uracil bases hold the place of all thymine bases until the newly formed double helix is able to form hydrogen bonds.

DNA helicases add nucleotides to the exposed bases and ensure the formation of hydrogen bonds

The answer is <span>DNA polymerases add nucleotides to the exposed base pairs according to base-pairing rules.

DNA polymerase performs the polymerization of DNA. It adds nucleotides to the new DNA strand according to the base-pairing rules. This means that adenine binds to thymine and guanine binds to cytosine. The DNA polymerase is important enzyme responsible for accurate DNA  replication.

Choice 2 is incorrect because DNA does not contain uracil.
Choice 3 is incorrect because helicase untwists DNA.</span>

Answer:

Charles Darwin

Explanation:

Natural selection, most famously proposed by Charles Darwin, states that when presented with an environmental challenge, some individuals in a species will develop adaptations to face these challenges. Successful individuals will be more likely to mate and their offspring will inherit these adaptive traits, and will continue to pass for generations.

In this sense, plants face the challenge of the cold. Those that adapt to the cold will survive and reproduce, those that can't adapt to the cold will die. Eventually, only plants that can tolerate the cold will survive.

Though I cannot write this essay for you, I can provide some information to get you started on the relationship between ancestry and evolution.

<h3 /><h3>How are ancestry and evolution related?</h3>

Ancestry and evolution share a close relationship in that we can use one to learn about the other. Evolution can be <u>traced </u>using ancestry. By analyzing the genetic information of ancestral species and using information gathered about the environment in which they lived, we can deduce the impact of evolution on said species. One possible example is that penguins used to be capable of flight, but given their mostly aquatic environments, have evolved wings more suited for swimming, and lost the ability to fly as a result.

Therefore, we can say that ancestry and genetic information can be used to support the theory of evolution by examining how two species can be very different but share a common ancestor, and evolution can explain these changes.
