NEET BIOLOGY

Detailed explanation-1: -During anaphase, the sister chromatids are separated simultaneously at their centromeres. The separated chromosomes are then pulled by the spindle to opposite poles of the cell. Anaphase ensures that each daughter cell receives an identical set of chromosomes.

Detailed explanation-2: -Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate.

Detailed explanation-3: -Anaphase I: In anaphase I, the attachment of the spindle fibers is complete. The homologous chromosomes are pulled apart and move towards opposite ends of the cell.

Detailed explanation-4: -During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle.

Detailed explanation-5: -The splitting of centromere does not occur in anaphase I but occurs in anaphase II. Anaphase is the stage of mitosis or meiosis when chromosomes are split and the sister chromatids move to opposite poles of the cell.
