Question

Quizplus · Accepted Answer

The spontaneous change of a nitrogenous base to a slightly distinct form is called tautomerization. This can occur due to the shifting of hydrogen atoms in the base, leading to a temporary alteration in its structure. Tautomerization can lead to mutations in DNA, as the altered base may pair with an incorrect partner base during replication.
