Some bacteria have been found to have much higher rates of mutation than other members of their populations;they are termed "mutators." What do you think is the reason for their faster rates of mutation?
A)They have much smaller genomes than regular bacteriA.
B)They are much better at bacterial transformation than regular bacteria.
C)They are incapable of bacterial transformation.
D)Their DNA polymerase has compromised 3' to 5' proofreading function.
E)Their DNA polymerase has compromised 5' to 3' polymerase function.

Question

Quizplus · Accepted Answer

The faster rates of mutation in mutator bacteria are likely due to a compromised 3' to 5' proofreading function in their DNA polymerase. This means that errors made during DNA replication are not corrected as effectively, leading to a higher mutation rate.
