Restriction enzymes are called as molecular scissors as they cut DNA at close recognition sites known as restriction sites. They make a single incision on each DNA strand , they are also called as restriction endonucleases and DNA scissors also. Plasmid refers to the separated DNA molecule from chromosomal DNA, which has the ability to replicate on its own. DNA Polymerases are a group of enzymes that catalyse the synthesis of DNA during replication. DNA ligase is used to join two fragments of DNA to seal the gaps between them.
