5.10 describe the use of restriction enzymes to cut DNA at specific sites and ligase enzymes to join pieces of DNA together

5.10 •enzymes can cut up DNA or join DNA together 

                  •restriction enzymes recognise specific sequences of DNA and cut the DNA at these points

                  •ligase enzymes are used to join the two pieces of DNA together 

                  •two different bits of DNA stuck together are know as recombinant DNA
