Tautomeric shift is a form of

DNA damage and occurs when any of the 4 bases undergoes spontaneous

to form a

isomer, also known as a

This can lead to incorrect base pairing between the tautomeric bases. Examples include the conversion of an amino group to an

group via the loss of a

from an NH2 group, as well as the formation of an

group (C-OH) from a

group (C=O) via addition of a

atom.
