Many eukaryotes have a DNA glycosylase that specifically removes T residues from DNA when paired with G. Why is it better to repair the G-T pairing to G-C by removing the T than to remove the G and form an A-T pair?
A. G-C pairs can form three hydrogen bonds between them and are therefore stronger. B. Oxidative damage to guanine by alkylation is the most common reason for G-T pairs, so removal of the T will maintain the original G-C pair. C. T bases easily tautomerize into C bases, so removing the T will make sure the pair stays in its original form. D. G-C basepairs occur more frequently in cells. E. All of the choices provided are potential reasons.
