Within a double-stranded DNA molecule, an A on one strand is paired with a G on the other.Which DNA repair system would most likely fix this error?
A) Proofreading
B) Excision
C) Ligase
D) Mismatch
E) Template

Question

Quizplus · Accepted Answer

The mismatch repair system recognizes and repairs mispaired bases, such as an A/G base pair mismatch. Proofreading occurs during DNA replication and corrects errors as they occur. Excision repair removes damaged DNA, such as from UV radiation or chemical exposure. Ligase joins Okazaki fragments during DNA replication. Template repair is not a known DNA repair system.
