select the correct answer.\nwhy do you think the eukaryotic dna requires multiple origins of replication?\na. multiple origins help make more copies of the same dna simultaneously.\nb. eukaryotic organisms have unique dna strands for each specialized cell.\nc. eukaryotes do not have topoisomerase, so multiple origins are created due to tension from unwinding of dna strands.\nd. eukaryotic dna is much larger and replication at multiple origins helps reduce the time required for whole genomes to replicate.\ne. multiple origins of replication ensure that there are no lagging strands and replication takes place at the same pace.

Answer

Brief Explanations:

Eukaryotic DNA is large. Multiple origins allow different parts of the DNA to replicate simultaneously, reducing the overall replication time for the entire genome. Option A is incorrect as it's not about making more copies at once but speeding up whole - genome replication. Option B is wrong because eukaryotic cells of an organism have the same DNA (though differential gene expression occurs). Option C is incorrect since eukaryotes have topoisomerase. Option E is wrong as lagging strands are still formed in DNA replication even with multiple origins.

Answer:

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