Answer and explanation
Correct answer: D. Interphase, before the cell divides
- Step 1: Each chromosome is copied during the S phase of interphase.
Answer
Interphase, before the cell divides.
Why not the others: Prophase, when the chromosomes become visible: DNA has already been copied by prophase. Anaphase, when the chromatids separate: separation happens after replication is complete. Cytokinesis, when the cytoplasm divides: cytokinesis follows nuclear division.
