WebThere are several major types of DNA-manipulation enzymes used by living cells. The first type is DNA polymerase, which cells use to replicate their own DNA. The next type is DNA ligase, which joins 2 pieces of DNA to create a single piece. The third type is restriction enzymes, which appear to be made only by bacteria.
