In meiosis, which part is most similar to mitosis in terms of separating sister chromatids?
A
Meiosis II (especially anaphase II), when sister chromatids separate
B
Prophase I, when crossing over occurs between homologous chromosomes
C
Interkinesis, when DNA is replicated between meiosis I and II
D
Meiosis I (anaphase I), when homologous chromosomes separate
검증된 단계별 안내1
Understand the key difference between mitosis and meiosis: mitosis separates sister chromatids, while meiosis separates homologous chromosomes in the first division and sister chromatids in the second division.
Recall that in meiosis I, homologous chromosomes are separated, which is different from mitosis where sister chromatids separate.
Identify that crossing over occurs during Prophase I of meiosis, which is unique to meiosis and not seen in mitosis.
Note that interkinesis is a resting phase between meiosis I and II where no DNA replication occurs, unlike the S phase before mitosis.
Recognize that meiosis II, especially anaphase II, is most similar to mitosis because sister chromatids separate during this phase, just like in mitosis.
