Question

Determine whether the characteristics describe DNA replication in prokaryotes only, eukaryotes only, or both prokaryotes and eukaryotes.

There are multiple origins of replication.

Replication occurs in the cytoplasm.

DNA is synthesized in a 5′ to 3′ direction.

There is one origin of replication. DNA polymerase synthesizes the new DNA strand.

Replication occurs in the nucleus.

Answer 1

Correct answer: Both prokaryotes and eukaryotes

DNA replication is the biological process of making two identical copy of DNA from the original DNA. It consists of three steps initiation, elongation and termination.

The prokaryotic DNA contains single origin of replication while the eukaryotic DNA contains multiple origin of replication. In prokarotes DNA replication takes place inside the cytoplasm while in eukaryotes it take place in the nucleus.

In prokaryotes DNA Polymerase I start the replication in 5' to 3' direction while in eukaryotes DNA polymerase α start the replication in 5' to 3' direction.

So, based on these characteristics it can be said that it occurs in both prokaryotes and eukaryotes.

Answer 2

"The characteristics describe DNA replication in both prokaryotes and eukaryotes.

DNA replication is the process of making two identical copies of DNA from the original one.

The prokaryotic DNA is of single origin and is placed inside the cytoplasm. The  eukaryotic DNA is of multiple origin and is placed in the nucleus.
