Hello Littlefoot2645. I do believe the answer would be that of the process of "mutation," thus it occurs by human interference, specifically, although, initially, naturally-speaking, only occurring by natural selection in onslaught of period time frames.
Answer:
D
it's Ddddddddddddddddddddddd
Explanation:
D
The two enzymes that are used during DNA replication is helicase
and polymerase. Each enzyme has distinct role that made it a vital part of the replication.
In the course of DNA replication, the initial stage is to unzip the double
helix structure of the DNA molecule by the enzyme helicase, which breaks the
hydrogen bonds that holds the complementary bases of DNA.
Moreover, the DNA polymerase has the ability to exactly copy a
DNA template. This enzyme binds to the leading strand and then adding a new
complementary nucleotide bases to the DNA strand. In addition, it catalyzes the joining of
deoxyribonucleoside 5′-triphosphates (dNTPs) to form the increasing DNA chain.
