Question

How does DNA replication take place?

Answer 1

DNA replication occurs in the nucleus of eukaryotic cell. By definition, prokaryotic cells do not have nuclei. Therefore, DNA replication occurs in the cytoplasm of a prokaryotic cell.

Answer 2

The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands.
