Which enzyme is responsible for creating the covalent bonds (specifically phosphodiester bonds) that connect the sugar-phosphate backbone of the new DNA molecules?
DNA ligase is an enzyme that repairs irregularities or breaks in the backbone of double-stranded DNA molecules. ... It has three general functions: It seals repairs in the DNA, it seals recombination fragments, and it connects Okazaki fragments (small DNA fragments formed during the replication of double-stranded DNA).
