Question

Quizplus · Accepted Answer

Ligase enzymes join two pieces of DNA by catalyzing the formation of a phosphodiester bond between the 3' hydroxyl group of one DNA fragment and the 5' phosphate group of another. This makes ligase the best choice for joining two DNA fragments in the process of gene cloning.
