Question

In the study of evolutionary relationships, the concept of the molecular clock assumes:
a) Changes only occur in key genes such as the 16S rRNA gene
b) Most nucleotide changes will affect the structure or function of the protein encoded by the
gene
c) Nucleotide changes accumulate in proportion to time
d) Changes never occur in key genes such as the 16S rRNA gene

@aaronq I would say a, because it is how they classify bacteria?

Answer 1

I think you are right.

Answer 2

I think it's c) Nucleotide changes accumulate in proportion to time
