Question

during which phase of the cell cycle does dna duplication, or replication, take place?
○ prophase
○ metaphase
○ interphase
○ anaphase

Explanation:

To determine when DNA replication occurs in the cell cycle, we analyze each phase:

• Prophase: Involves chromosome condensation and spindle formation, no DNA replication.
• Metaphase: Chromosomes align at the equator, no DNA replication.
• Interphase: Consists of G1, S, and G2 phases. DNA replication (duplication) happens during the S (synthesis) phase of Interphase.
• Anaphase: Sister chromatids separate, no DNA replication.

Answer:

C. Interphase
