The molecule(s) that act as molecular glue to bind DNA fragments together is/are
A) DNAse.
B) DNA ligase.
C) ligandase.
D) polymerase.
E) DNAse AND ligandase.

Question

Quizplus · Accepted Answer

DNA ligase is the enzyme that acts as molecular glue to bind DNA fragments together. It forms phosphodiester bonds between the 3'-hydroxyl group and the 5'-phosphate group of adjacent nucleotides, thus creating a continuous DNA strand. DNAse is an enzyme that degrades DNA, while ligandase is not a known enzyme. Polymerase is an enzyme that synthesizes DNA and does not directly bind DNA fragments. Therefore, the correct answer is B.
