In what manner does dna replicate in
Web16 jul. 2016 · 3. DNA replication likes one direction. Not the boy band, but rather it prefers to replicate in a certain direction over the other. Publishing their findings in Science Advances, scientists have discovered an enzyme that can perform the procedure in the opposite direction and characterized how it works - a complex process. 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. Primase activity needs the formation of a complex of primase and at ...
