Dna replication occurs during which phase of the eukaryotic cell cycle?

In eukaryotic cells the DNA can be found in the nucleus mainly. so DNA replication takes place in the nucleus during the S phase of the cell cycle.

Also in eukaryotic cells there are mitochondria and chloroplasts (plants) and these have circular DNA and they also get replicated (according to their own mechanism).

Prokaryotic cells don't contain a nucleus. They do not contain DNA in the cytoplasm and thus the DNA replication will take place here.

I really hope this helps!

b.have there own function.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link:
