Ligation may refer to:
- Ligation (molecular biology), the covalent linking of two ends of DNA or RNA molecules, most commonly done using DNA ligase, RNA ligase (ATP) or other enzymes.
- In medicine, the making of a ligature (tie)
- Chemical ligation, the production of peptides from amino acids
- Tubal ligation, a method of female sterilization
- Rubber band ligation, a treatment for hemorrhoids
- In Coordination chemistry, making a bond between a ligand and a Lewis acid
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. The ends of DNA fragments are joined together by the formation of phosphodiester bonds between the 3'-hydroxyl of one DNA terminus with the 5'-phosphoryl of another. RNA may also be ligated similarly. A co-factor is generally involved in the reaction, and this is usually ATP or NAD.
Ligation in the laboratory is normally performed using T4 DNA ligase, however, procedures for ligation without the use of standard DNA ligase are also popular.
