Question
After which phase in the cell cycle and DNA replication, meiosis begins?
Interphase
Cytokinesis
G1phase
G2 phase
Interphase
Cytokinesis
G1phase
G2 phase
Hint:
Interphase is the phase in the cell cycle and DNA replication, meiosis begins
The correct answer is: Interphase
- Before entering meiosis I, cells must first pass through interphase. This is the same intermediate stage that occurs before mitosis.
- The cell grows, copies its chromosomes, and prepares for division during the interphase G 1 start subscript, 1, end subscript S and G 2 start subscript 2, end subscript phases.
