E)methylase enzymE.

Question

Quizplus · Accepted Answer

Ligase enzyme is responsible for sealing the two strands of DNA that have been cut by an endonuclease. Polymerase enzymes are responsible for adding nucleotides to a single strand of DNA during replication. Exonuclease enzymes are responsible for removing nucleotides from the end of a DNA strand. Protease enzymes are responsible for breaking down proteins while methylase enzymes add methyl groups to DNA.
