Question
After which phase in the cell cycle and DNA replication, meiosis begins?
Interphase
Cytokinesis
G1phase
G2 phase
Interphase
Cytokinesis
G1phase
G2 phase
Hint:
This is the first stage of meiosis I.
The correct answer is: Interphase
- Meiosis involves not only one fission but two.
- Despite this fact, many of the other events in meiosis are similar to those occurring in mitosis.
- For example, before meiosis, cells go through an intermediate stage to grow, replicate chromosomes, and check all systems to ensure they are ready for division.
