when changes in a protein appear to accumulate at a constant rate over time is called option (c) i.e, Molecular clock.
<h3>What does molecular clock mean?</h3>
The term "molecular clock" refers to a method that estimates the time in prehistory when two or more life forms diverged by analyzing the mutation rate of biomolecules. Typically, nucleotide sequences for DNA, RNA, or amino acid sequences for proteins serve as the biomolecular data for these calculations.
Hedges, a biology professor at Penn State, claims that the molecular clock counts the mutations that accumulate through time in the gene sequences of various species rather than counting seconds, minutes, and hours.
Mutation and recombination, the two fundamental biological processes that give rise to all heritable variations, are the foundation of molecular clocks. Mutations are modifications to the genetic code of DNA, for as when the nucleotide Guanine (G) turns to Thymine (T).

Answer:
CTAGCA
Explanation:
During DNA replication, the DNA double helix is unwound by DNA helices. Each original strand is then used as a template, by the DNA polymerase, to synthesize a new strand. Base pairing rules apply in the synthesis. Cytosine pairs with Guanine while Adenine pairs with Thiamine.
