Spontaneous hydrolysis reactions between DNA and surrounding water molecules commonly cause
A)pyrimidine dimer formation.
B)depurination.
C)tautomeric shift.

E)deletion mutations.

Question

Quizplus · Accepted Answer

Depurination is a common spontaneous hydrolysis reaction where the glycosidic bond between a purine base (adenine or guanine) and the deoxyribose sugar is broken, leading to the loss of the purine base from the DNA molecule.
