Question

Quizplus · Accepted Answer

Maintenance methylase is responsible for adding methyl groups to the newly synthesized DNA strand in order to maintain the methylation pattern from the parent strand. Without maintenance methylase, the changes made by DNA methylase would not be passed on from one generation to the next, as the newly synthesized DNA strands would not be methylated. The other choices are not directly affected by the absence of maintenance methylase.
