Which of the following statement is correct regarding the process of replication in $E$.coli?
The $DNA$ dependent $RNA$ polymerase catalyses polymerization in one direction, that is $5^{\prime} \rightarrow 3^{\prime}$
The $DNA$ dependent $DNA$ polymerase catalyses polymerization in $5^{\prime} \rightarrow 3^{\prime}$ as well as $3^{\prime} \rightarrow 5^{\prime}$ direction
The $DNA$ dependent $DNA$ polymerase catalyses polymerization in $5^{\prime} \rightarrow 3^{\prime}$ direction
The $DNA$ dependent $DNA$ polymerase catalyses polymerization in one direction that is $3^{\prime} \rightarrow 5^{\prime}$
Solution
In Prokaryotes, like E.coli during replication, the DNA dependent DNA polymerase catalyse polymerization only in one direction, that is $5^{\prime} \rightarrow 3^{\prime}$
