Question

Where does DNA replication occur?

Answer 1

DNA replication:

1. DNA replication occurs at the S-stage (synthesis) of the cell cycle before mitosis.
2. Semi-conservative replication employs each strand of the original DNA molecule as a template for the production of its counterpart.
3. As the semi-conservative replication results, original DNA strands and newly synthesized strands make the new helix.
4. Cellular error-checking and proofreading systems provide near-perfect DNA replication fidelity.

Location of DNA replication:

1. DNA is located in a cell's nucleus in humans.
2. Since the nucleus is where the DNA is located, replication occurs there.
