Answer:
Scientists who wish to clone genes of interest into bacterial plasmids utilize restriction enzymes which cuts the target and vector DNA at specific sites. Then DNA ligase is used to form covalent bonds between the resulting fragments to complete the recombinant DNA molecule.
Explanation:
Restriction enzymes can be described as the class of enzymes which can break down DNA at specific sites. There are multiple kinds of restriction enzymes which have the ability to cut the DNA at specific locations. The cutting of the restriction enzymes might produce sticky or blunt ends.
DNA ligases are the enzymes which are used to seal the DNA or join them at specific sites.
