Which of the following statement is correct regarding the process of replication in E.coli?

The DNA dependent DNA polymerase catalyses polymerization in \( 5' \rightarrow 3' \) as well as \( 3' \rightarrow 5' \) direction.
The DNA dependent DNA polymerase catalyses polymerization in \( 5' \rightarrow 3' \) direction.
The DNA dependent DNA polymerase catalyses polymerization in one direction that is \( 3' \rightarrow 5' \).
The DNA dependent RNA polymerase catalyses polymerization in one direction, that is \( 5' \rightarrow 3' \).

Correct answer · Option 2

The DNA dependent DNA polymerase catalyses polymerization in \( 5' \rightarrow 3' \) direction.

The DNA-dependent DNA polymerase catalyzes the polymerization of deoxynucleotides only in one direction, which is \( 5' \rightarrow 3' \).
