What is ligase in DNA replication in a very short and simple explanation

Ligase is an enzyme that plays a critical role in DNA replication by joining or "gluing" together the small fragments of DNA that are synthesized on the lagging strand of the replication fork. It helps ensure that the entire DNA strand is continuous and complete.

Ligase is an enzyme involved in DNA replication that helps to join (ligate) the Okazaki fragments on the lagging strand. It acts as a "molecular glue" by catalyzing the formation of strong chemical bonds between adjacent DNA fragments, creating a continuous DNA strand.
