Where does DNA replication occur in eukaryotic cells?

Explanation:
DNA replication in eukaryotic cells occurs in the nucleus. The bulk of a eukaryotic genome is organized into chromosomes housed behind the nuclear envelope, and the replication machinery—DNA polymerases, helicases, primases, ligases, and licensing factors—works on these chromosomal templates during S phase. The nucleus provides the controlled environment and access needed to duplicate all chromosomes properly before cell division. Mitochondria do have their own DNA that replicates inside the organelle, and ribosomes and cytoplasm are more associated with protein synthesis, not DNA replication. So the nucleus is the correct location for replicating the nuclear genome.
