The correct order of events for synthesis of the lagging strand is
1 Primase adds primer, DNA polymerase I removes the primer, DNA polymerase extends the segment, the ligases seals the gap.
2 Primase adds RNA primer, DNA polymerase III creates a stretch, DNA polymerase I removes the primer, and ligase seals the gaps.
3 Helicase unwinds the DNA, primase creates a primer, DNA polymerase I elongates the stretch, DNA polymerase III removes the primer, and ligase seals the gaps in the DNA.
4 Ligase adds bases to the primase, the primase generates the polymerase I, polymerase III adds to the stretch, helicase winds the DNA.
Explanation:
The correct order of events for synthesis of the lagging strand is primase adds RNA primer, DNA polymerase III creats a stretch, DNA polymerase I removes the primer, and ligase seals the gaps.

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