Question
DNA makes a copy of itself in_________.
- Prophase
- Anaphase
- Interphase
- Telophase
Hint:
This phase is also called S phase.
The correct answer is: Interphase
- Cell cycle consists of S phase and M phase, with gap phases in between
- S phase is also called interphase
- During S phase, the genetic material or DNA replicates, making a copy of itself
- The number of chromosomes is doubled during interphase
- Following S phase, the mitosis occurs, where the cell divides and the chromosomes are split between the two daughter cells produced
