Question

RNA primase synthesizes RNA primer that attaches itself at the initiation point of replication. RNA primer constructed during DNA replication needs to be replaced because RNA differs from DNA. Instead of why do you think the eukaryotic DNA requires multiple origins of replication?

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

Answer 1

Eukaryotic DNA requires multiple origins of replication for more efficient and accurate replication, especially due to the unique DNA strands in specialized cells and the larger size of eukaryotic DNA.

Step-by-step explanation:

Eukaryotic DNA requires multiple origins of replication for several reasons. First, multiple origins help make more copies of the same DNA simultaneously, which allows for faster replication.

Second, eukaryotic organisms have unique DNA strands for each specialized cell, and multiple origins ensure that each DNA strand is replicated accurately.

Third, eukaryotic DNA is much larger than prokaryotic DNA, and replication at multiple origins helps reduce the time required for the entire genome to replicate.
