What is true of the comparison between the myosin of a rat and a mouse?
A)The nucleotide sequences are identical.
B)The genes encode for different proteins.
C)Each species has accumulated random mutations,but the sequences are similar.
D)Both species are so far apart that there is no homology between the two sequences.
E)The genes encoding myosin closely resemble those encoding actins.

Question

Quizplus · Accepted Answer

The comparison between myosin of a rat and a mouse reveals that each species has accumulated random mutations, but the sequences are still similar. Therefore, Option C is the correct answer. Option A and B are incorrect because nucleotide sequences are not identical and genes encode for different proteins. Option D is incorrect because even if the two sequences are far apart, they can still have homology. Option E is also incorrect because the myosin and actins are two different proteins, and their encoding genes are not closely related.
