The following points highlight the seven important enzymes involved in the process of DNA replication of prokaryotes. The enzymes are: 1. DNA Polymerase 2. Primase 3. Polynucleotide Ligase 4. Endonucleases 5. Pilot Proteins 6. Helicase 7. Single-Strand Binding (SSB) Protein. Enzyme # 1. DNA Polymerase: DNA polymerase is the chief enzyme of DNA replication. DNA […]
In this article we will discuss about a generalised model of DNA replication in prokaryotes. DNA replication is catalyzed by the enzyme DNA polymerase, and it involves several other proteins/enzyme. The data collected from both in vitro and in vivo studies have been synthesized into a generalized model DNA replication, a brief and simplified description […]
Theoretically, there are the following three possible modes of DNA replication: (1) Dispersive, (2) Conservative and (3) Semi-conservative. 1. Dispersive Replication: In dispersive replication, the parent DNA molecule is broken into several pieces, and the ‘new’ molecules will consist of both old and newly synthesized segments. In the conservative scheme, the two ‘old’ strands would […]
