Catalyses DNA-template-directed extension of the 3'- end of an RNA strand by one nucleotide at a time. But DNA polymerase require primer to initiate the replication. Antonyms for DNA-dependent DNA polymerase. After the activated polymerase has attached to the DNA, it will break down the molecule of ATP to free itself from the DNA. Key Difference – DNA Ligase vs DNA Polymerase DNA ligase and DNA polymerase are important enzymes involved in DNA replication and DNA repair mechanisms of organisms.
