3 Main Enzymes of DNA Replications | Cell Biology

The 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 least six [...]

Continuous and Discontinuous Replication | Cell biology

The upcoming discussion will update you about the difference between Continuous and Discontinuous Replication. Difference # Continuous Replication: 1. Occurs on leading of a replication fork. 2. Starts at the beginning of replication. 3. Progresses in on direction, i.e., towards the replication fork. 4. Synthesis of DNA takes place continuously. 5. In vivo need no RNA primer. 6. Only DNA [...]

4 Main Replications of DNA | Cell Biology

The following points highlight the four main replications of DNA. The replications are: 1. Plasmid 2. Mitochondrial DNA 3. Kinetoplast DNA 4. Chloroplast DNA. Replication # 1. Plasmid: In addition to the nucleoid DNA, the cytoplasm of bacterial cell contains one or more extra chromosomal mini-circular DNA duplexes which are known as plasmids that can replicate independently of the nucleoid [...]
