During anaphase II of meiosis, what is the key event that occurs in each cell?
A
Sister chromatids separate at their centromeres and move to opposite poles of the cell.
B
Homologous chromosomes separate and move to opposite poles of the cell.
C
Crossing over occurs between non-sister chromatids of homologous chromosomes.
D
DNA replication occurs to prepare chromosomes for division.
검증된 단계별 안내1
Recall the stages of meiosis, focusing on the differences between meiosis I and meiosis II.
Understand that during meiosis I, homologous chromosomes separate, while during meiosis II, sister chromatids separate.
Identify that anaphase II is a phase in meiosis II, which follows meiosis I and the second round of cell division.
Recognize that the key event in anaphase II is the separation of sister chromatids at their centromeres, moving toward opposite poles of the cell.
Note that crossing over occurs earlier during prophase I, and DNA replication happens before meiosis begins, not during anaphase II.
