Neutral theory proposes that
A)molecular clocks are more reliable when the surrounding pH is close to 7.0.
B)most mutations of highly conserved DNA sequences should have no functional effect.
C)DNA is less susceptible to mutation when it codes for amino acid sequences whose side groups (or R groups)have a neutral pH.
D)DNA is less susceptible to mutation when it codes for amino acid sequences whose side groups (or R groups)have a neutral electrical charge.
E)a significant proportion of mutations is not acted upon by natural selection.

Question

Quizplus · Accepted Answer

Neutral theory proposes that a significant proportion of mutations is not acted upon by natural selection, and are therefore subject to genetic drift. This means that these mutations can arise and persist in a population even if they have no functional effect, which is a central tenet of neutral theory. Neutral theory does not specifically address molecular clocks, pH, or the susceptibility of DNA to mutation based on the charge or pH of amino acid side groups.
