What enzymes are used in DNA replication? Socratic

WebSection Summary. DNA replicates by a semi-conservative method in which each of the two parental DNA strands act as a template for new DNA to be synthesized. After replication, each DNA has one parental or “old” strand, and one daughter or “new” strand. Errors made during replication are typically repaired. WebThe following points highlight the three main enzymes of DNA replications. The enzymes are: 1. Primase 2. DNA Polymerase 3. DNA Ligases. Enzyme # 1. Primase: A primase is an enzyme which makes the RNA primers required for initiation of Okazaki pieces on the lagging strand.
