Answer:
D. Ligase
Explanation:
Ligase is an enzyme that can catalyze the fusion of two large molecules through the formation of a new chemical bond, which is usually accompanied by the hydrolysis of a small end chemical group.
Ligases play an important role in linking DNA breaks during excision repair, DNA damage, or spontaneous lesions such as basal sites or oxidized bases.
