Vedclass · Answer

(C) During $DNA$ replication, the $RNA$ primers are removed by the $5' 	o 3'$ exonuclease activity of $DNA$ polymerase-$I$ in prokaryotes. After the removal of $RNA$ primers, the gaps are filled by the $DNA$ polymerase activity of $DNA$ polymerase-$I$ in prokaryotes. In eukaryotes, the removal of $RNA$ primers and the subsequent filling of gaps is primarily carried out by $DNA$ polymerase-$\alpha$ (which has primase activity) and $DNA$ polymerase-$\delta$ or $\epsilon$. Therefore, the correct sequence is: $i = 	ext{DNA polymerase-}I$, $ii = 	ext{DNA polymerase-}I$, and $iii = 	ext{DNA polymerase-}\alpha$.

During replication of $DNA$, the $RNA$ primers are removed by i and replaced by $DNA$ sequences with the help of ii in prokaryotes and iii in eukaryotes.
