What is ligases ? |
| Answer» Ligases\xa0are\xa0enzymes\xa0that are capable of catalyzing the reaction of joining two large molecules by establishing a new chemical bond, generally with concomitant hydrolysis of a small chemical group on one of the bulky molecules or simply linking of two compounds together.\xa0DNA\xa0ligase is the enzyme at the heart of the DNA ligation reaction. It covalently joins the phosphate backbone of DNA with blunt or compatible cohesive ends (see Figure 1) and it\'s natural role is in repairing double strand breaks in DNA molecules. | |
