Which of the following statements is TRUE regarding the molecular clock of hemoglobins?
A)Given the high rate of mutations that occur in the DNA coding regions of hemoglobin genes, the molecular clock of hemoglobins is much faster than that of pseudogenes.
B)Given the robust action of negative selection on deleterious mutations in hemoglobin genes, the molecular clock of hemoglobins is much slower than that of histones.
C)The molecular clock of hemoglobins could be considered to be at a "standstill," as mutations in hemoglobin genes are usually not affected by natural selection.
D)The rate of the molecular clock of hemoglobins is in between that of pseudogenes and histones.

Question

Quizplus · Accepted Answer

The molecular clock of hemoglobins evolves at a rate that is slower than pseudogenes, which are not subject to functional constraints, but faster than histones, which are highly conserved due to their critical role in DNA packaging.
