Select the correct answer.

Why do you think 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.
D. Eukaryotic DNA is much larger and replication at multiple origins helps reduce the time required to replicate.

Final answer:

Eukaryotic DNA requires multiple origins of replication to efficiently replicate large genomes in a timely manner.


Explanation:

Eukaryotic DNA requires multiple origins of replication due to the size and complexity of eukaryotic genomes. In eukaryotes, with multiple linear chromosomes, each chromosome needs more than one origin of replication to duplicate in the S-phase of the cell cycle.

Having multiple origins of replication ensures quicker replication by allowing simultaneous initiation of DNA synthesis at different points along each chromosome. This mechanism helps eukaryotic cells efficiently replicate their large genomes within a reasonable time frame.

Moreover, the presence of multiple origins of replication in eukaryotic DNA helps prevent lagging strands and ensures smooth replication across the entire chromosome.
