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

SVEN [57.7K]

Explanation:

DNA replication is a process common to both prokaryotes and Eukaryotes with few differences and similarities.

<u>Differences:</u>

1. Origin of replication (ori) : is a sequence of the genome where initiation of replication takes place. Prokaryotes have only single ori while eukaryotes have multiple ori as the DNA is large in eukaryotes so require multiple or to replicate whole DNA.

2. Replication site: prokaryotes lack nucleus where DNA is present in the cytoplasm while eukaryotes posses nucleus which encloses DNA. Therefore, replication takes place in cytoplasm in prokaryotes while in the nucleus in eukaryotes.

<u>Similarities:</u>

1. Enzymes: both posses same enzymes for DNA replication like DNA helicase, primase, polymerase.

2. The direction of synthesis: the enzyme DNA polymerase synthesizes new strand of DNA in the same direction that is 5' to 3' direction.

Thus, marked answer in the table are correct answer.
