ligase enzyme

Ligase is an enzyme that acts like a molecular glue, connecting two strands of DNA or other molecules. Its main role is to seal gaps or nicks in the DNA backbone, which often occur during processes like DNA replication or repair. By forming new bonds between nucleotides, ligase maintains the integrity and stability of genetic material. This function is essential for cells to accurately copy and fix their DNA, ensuring proper genetic information transmission and preventing mutations. In biotechnology, ligase is also used to join DNA pieces together in genetic engineering.
