Polymerisation of DNA nucleotides during the synthesis of lagging strand occurs in:
1 3' \(->5\) ' direction
2 5 ' \(->\) ' direction
3 Any direction
4 Promotor to terminator direction
Explanation:
DNA synthesis takes place only in \(5^{\prime} \rightarrow 3^{\prime}\) direction in both leading and lagging strand. Lagging strand (template having \(5^{\prime} \rightarrow 3^{\prime}\) polarity) that grows away from replication fork is synthesized discontinuously because initiation of each fragment must wait for the parental strands to separate and expose additional template.

RNA primer helps in :
1 Transcription
2 Translation
3 Replication
4 Transformation
Explanation:
A primer is a short strand of RNA which serves as a initial point for DNA synthesis. RNA primer is needed for DNA replication because the enzymes which catalyze this process, i.e.,DNA polymerases, is able to add new nucleotides only to an existing strand of DNA.

Which one statement regarding "Okazaki fragment" is in correct
1 Formed discontinuously
2 These are small single stranded fragments of DNA newly synthesised during DNA replication
3 These are fragments of mRNA
4 The template with polarity 5'3' is used
Explanation:
They are not fragments of mRNA.

The enzyme which helps to cut one strand of DNA duplex to release tension of coiling of two strands is:
1 DNA ligase
2 DNA polymerase I
3 Swielases (helicase or unwindases)
4 Topoisomerase
Explanation:
James. C. Wing first discovered an isomerase enzyme, topoisomerase that is involved in making cuts in DNA chain to relax the tangled DNA strands during the process of replication, recombinations or during viral genome integration into a host genome. To catalyze this process, the topoisomerase uses tyrosine residues.
