Question

Sort the statements based on whether they describe DNA replication in eukaryotes or prokaryotes. Replication takes place in the nucleus.There is only one origin of replication.There are multiple origins of replication.Replication happens at just one point on the chromosome.Replication takes place in the cytoplasm.Replication occurs at multiple points along the chromosome.

Answer 1

In eukaryotes, replication takes place in the nucleus as prokaryotes do not have a true nucleus and replication takes place in the cytoplasm. The nucleus of the eukaryotes is the location where genetic material (DNA) is found; in prokaryotes, the genetic material is condensed in the cytoplasm called the nucleoid. There are multiple replication forks or multiple origins of replication in eukaryotes in contrast to prokaryotes which only has one origin of replication. Lastly, replication in eukaryotes occurs at multiple points along the chromosome; in contrast with prokaryotes where it occurs at just one point on the chromosome.

Answer 2

Prokaryotes

The DNA molecule has only one origin of replication.

They lack a nucleus. The DNA replication takes place in the cytoplasm.

Replication happens at only a single point in each chromosome.

Eukaryotes

The DNA molecule unwinds at multiple locations. The DNA molecule has several origins of replication in each chromosome.

DNA is contained in the nucleus, so DNA replication occurs in the nucleus.

Each chromosome replicates as a section. Replication occurs simultaneously at several locations across the length of the chromosome.
