Answer:
D. Enzymes open the DNA strand, remove a segment of DNA from the strand that contains the damage, and resynthesize the correct DNA sequence.
Explanation:
From time to time, the DNA gets exposed to certain chemicals or radiation that damages it. However, the cell has a DNA repair mechanism in place called NUCLEOTIDE EXCISION REPAIR (NER).
NUCLEOTIDE EXCISION REPAIR (NER) is one of the DNA repair mechanisms in which certain enzymes open the DNA strand, remove a segment of DNA that contains the damaged gene or nucleotide bases, and resynthesize the correct DNA sequence using the pair of the damaged one.
In the gradual speciation<span> model, species diverge slowly over time in small steps while in the punctuated equilibrium model, a new species diverges rapidly from the parent species. The two key influencing factors on the change in </span>speciation rate<span>are the environmental conditions and the population size.</span>
