NEET BIOLOGY

Detailed explanation-1: -Sister chromatids separate during anaphase in a three-stage program as directed by interaxis bridges.

Detailed explanation-2: -Sister chromatids separate during anaphase in a three-stage program as directed by interaxis bridges.

Detailed explanation-3: -In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell. In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense.

Detailed explanation-4: -During anaphase of mitosis, the chromosomes split and the sister chromatids of each chromosome move towards the opposite poles. The separation of chromatids begins at the kinetochore and the arms trail behind.

Detailed explanation-5: -The absence of securin allows another enzyme called separase to act on cohesin molecules holding the two chromatids together. When cohesins are no longer resisting the pull of microtubules in the spindle, sister chromatids separate and move towards opposite poles.
