Ligation (molecular biology)
TECHNIQUE FOR JOINING DNA MOLECULES IN MOLECULAR BIOLOGY
Blunt-end ligation; DNA ligation
In molecular biology, ligation is the joining of two nucleic acid fragments through the action of an enzyme. It is an essential laboratory procedure in the molecular cloning of DNA, whereby DNA fragments are joined together to create recombinant DNA molecules (such as when a foreign DNA fragment is inserted into a plasmid).
