Question

Why do you think the eukaryotic DNA requires multiple origins of replication?

A.Multiple origins help make more copies of the same DNA simultaneously.
B.Eukaryotic organisms have unique DNA strands for each specialized cell.
C.Eukaryotes do not have topoisomerase, so multiple origins are created due to tension from unwinding of DNA strands.
D.Eukaryotic DNA is much larger and replication at multiple origins helps reduce the time required for whole genomes to replicate.
E.Multiple origins of replication ensure that there are no lagging strands and replication takes place at the same pace.

Answer 1

D

Step-by-step explanation:

Answer 2

Answer: D. Eukaryotic DNA is much larger and replication at multiple origins helps reduce the time required for whole genomes to replicate.

Due to the high amount of material to be replicated, there are multiple origin sites. DNA replication can independently initiated at each origin site and terminate at corresponding termination sites. Therefore, DNA replication at each origin site takes place simultaneously. This, reduces the time for replication of entire genome.
