In the process of meiosis, how many times does interphase occur before the two meiotic divisions begin?
A
Twice (one interphase before meiosis I and another before meiosis II)
B
Zero times (meiosis begins directly with prophase I without interphase)
C
Once (a single interphase occurs before meiosis I)
D
Three times (before prophase I, before metaphase I, and before meiosis II)
검증된 단계별 안내1
Understand that meiosis consists of two consecutive divisions: meiosis I and meiosis II.
Recall that interphase is the phase where the cell prepares for division by replicating its DNA and organelles.
Recognize that before meiosis I, the cell undergoes a single interphase, which includes the S phase where DNA replication occurs.
Note that after meiosis I, the cell enters meiosis II without another interphase; there is no DNA replication between meiosis I and meiosis II.
Conclude that interphase occurs only once before the start of meiosis I, and not before meiosis II.
