Question

Mention the functions of this 5 enzymes found in E. coli: DNA polymerase I, DNA polymerase II, DNA polymerase III, DNA polymerase IV, DNA polymerase V.

Answer 1

The functions of the enzymes in E.coli:

1. DNA Polymerase I - The function of this enzyme is to repair the DNA segments.

2. DNA Polymerase II - DNA polymerase II is involved in the replication process of the DNA of E.coli, but is not the main enzyme responsible for replication.

3. DNA polymerase III - It is the main DNA polymerase which is involved with the process of DNA replication.

4. DNA polymerase IV - It synthesizes transleions and is involved with non-targeted mutagenesis.

5. DNA Polymerase V - This is also involved with the transleions as an emergy response in E>Coli.
