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

Which of the following statement is correct regarding the process of replication in E.coli?
  1. The DNA dependent RNA polymerase catalyses polymerization in one direction, that is $5^{\prime} \rightarrow 3$ '
  2. The DNA dependent DNA polymerase catalyses polymerization in $5^{\prime} \rightarrow 3^{\prime}$ as well as $3^{\prime} \rightarrow 5$ ' direction
  3. The DNA dependent DNA polymerase catalyses polymerization in $5^{\prime} \rightarrow 3^{\prime}$ direction
  4. The DNA dependent DNA polymerase catalyses polymerization in one direction that is $3^{\prime} \rightarrow 5^{\prime}$

Solution

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