Which enzyme would be used to join two DNA fragments?
A) Reverse transcriptase
B) DNA polymerase
C) DNA recombinase
D) DNA endonuclease
E) DNA ligase

Question

Quizplus · Accepted Answer

DNA ligase is the enzyme responsible for joining two DNA fragments together by catalyzing the formation of a phosphodiester bond between the adjacent nucleotides on each strand of DNA. Reverse transcriptase and DNA polymerase are involved in DNA synthesis, while DNA recombinase and DNA endonuclease are involved in cutting and rearranging DNA sequences, not joining them together.
