Quizplus · Accepted Answer

A tautomeric shift is a temporary change in the conformation of a nitrogenous base, which can result in mispairing during DNA replication or cause spontaneous mutations. Depurination and deamination are permanent changes in the structure of a nitrogenous base, and they can also lead to mutations.
