Question

What are some contrasts between features of prokaryotic and eukaryotic DNA replication?

Answer 1

Prokaryotic and eukaryotic DNA replication have several contrasts in terms of rate, origins of replication, types of polymerases used, presence of telomerase, primer remover, and strand elongation.

Step-by-step explanation:

Some contrasts between features of prokaryotic and eukaryotic DNA replication include:

1. Rate of replication: Prokaryotic organisms generally have a faster rate of replication than eukaryotes.
2. Origins of replication: Prokaryotes have multiple origins of replication, while eukaryotes have a single site of origin.
3. Types of polymerases: Prokaryotes use a single type of polymerase for replication, while eukaryotes use multiple polymerases.
4. Presence of telomerase: Telomerase is absent in prokaryotes but present in eukaryotes.
5. Primer remover: Prokaryotes use DNA pol I as the primer remover, while eukaryotes use RNase H.
6. Strand elongation: Prokaryotes use DNA pol III for strand elongation, while eukaryotes use various polymerases such as pol ε and pol δ.
