(A) Tautomeric shifts are spontaneous changes in the molecular structure of nitrogenous bases in $DNA$. These shifts involve the migration of a hydrogen atom,which changes the base from its standard keto form to an imino or enol form. These alternative valence states allow for rare,incorrect base pairing (e.g.,$A$ pairing with $C$ instead of $T$),which can lead to mutations during $DNA$ replication.
