Title: DNA ligase
Post by: dexterm00 on Apr 17, 2014
Which statement best explains the distinction between the roles that DNA ligase and restriction enzymes perform in a DNA cloning experiment?

A.) DNA ligase generates hydrogen bonds between complementary base pairs, while restriction enzymes break those bonds.
B.) DNA ligase has a specific DNA recognition sequence, while restriction enzymes do not.
C.) DNA ligase generates the covalent bonds of the phosphodiester backbone, while restriction enzymes break those bonds.
D.) DNA ligase generates recombinant DNA by joining two different DNA molecules, while restriction enzymes convert long stretches of double-stranded DNA into two single-stranded DNA molecules.
