NEET (UG) 2024 — Question 142

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

Option A:
The DNA dependent DNA polymerase catalyses polymerization in one direction that is $3^{\prime} \rightarrow 5^{\prime}$
Option B:
The DNA dependent RNA polymerase catalyses polymerization in one direction, that is $5^{\prime} \rightarrow 3^{\prime}$
Option C:
The DNA dependent DNA polymerase catalyses polymerization in $5^{\prime} \rightarrow 3^{\prime}$ as well as $3^{\prime} \rightarrow 5^{\prime}$ direction
Option D:
The DNA dependent DNA polymerase catalyses polymerization in $5^{\prime} \rightarrow 3^{\prime}$ direction
Correct

Answer: D

Step-by-step solution

In Prokaryotes, like E.coli during replication, the DNA dependent DNA polymerase catalyse polymerization only in one direction, that is $5^{\prime} \rightarrow 3^{\prime}$
