Web1.)We engineered restriction enzymes into the forward and reverse PCR primers so that the amplified fragment could be digested with restriction enzymes and cloned into the expression plasmid. Why would AccI not be a good choice to use as a restriction enzyme in our forward primer? a. Because this restriction site is not in the plasmid . b. WebMar 16, 2024 · Restriction enzymes cleave the covalent phosphodiester between sugar and phosphate, hydrogen bonds that hold together two complementary nitrogen bases are weak bonds that do not require any enzyme-mediated separation. A restriction enzyme, also known as a restriction endonuclease, or a restrictase is an enzyme that cleaves the DNA …
