During which phase of mitosis do the sister chromatids separate
|
|
prophase
|
|
|
telophase
|
|
|
anaphase
|
|
|
metaphase
|
Explanation:
Detailed explanation-1: -A central feature of mitosis is segregation of sister chromatids to opposite poles during anaphase.
Detailed explanation-2: -Metaphase leads to anaphase, during which each chromosome’s sister chromatids separate and move to opposite poles of the cell. Enzymatic breakdown of cohesin-which linked the sister chromatids together during prophase-causes this separation to occur.
Detailed explanation-3: -In anaphase I, the homologous chromosomes are separated. In prometaphase II, microtubules attach to the kinetochores of sister chromatids, and the sister chromatids are arranged at the midpoint of the cells in metaphase II. In anaphase II, the sister chromatids are separated.
