Replication of DNA occurs before mitosis, during the S phase (Synthesis phase) of the interphase, not during mitosis itself.
- Mitosis involves the division of the nucleus and includes:
- (A) Condensation of the chromosomes – Happens in prophase
- (B) Breakdown of the nuclear membrane – Occurs in prometaphase
- (D) Spindle formation – Happens in prophase and metaphase
Summary:
- Interphase: DNA replication
- Mitosis: Chromosome sorting and cell division
