NEET BIOLOGY

Detailed explanation-1: -During anaphase identical sister chromatids separate and move towards opposite poles of the mitotic spindle . In the spindle, kinetochore microtubules have their plus ends embedded in the kinetochore and their minus ends at the spindle pole.

Detailed explanation-2: -Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate. The kinetochore spindle fibers shorten, allowing for 46 of the newly-freed chromatids to be dragged to one end of the cell and the remaining 46 chromatids to be dragged to the opposite end of the cell.

Detailed explanation-3: -The separation of homologous chromosomes or sister chromatids relies on them being pulled apart by microtubules. One end of each microtubule is attached to a protein-based structure called a kinetochore, which is assembled onto the centromere of each chromosome.

Detailed explanation-4: -Metaphase leads to anaphase, during which each chromosome’s sister chromatids separate and move to opposite poles of the cell.

Detailed explanation-5: -The sister chromatids are pairs of identical copies of DNA joined at a point called the centromere. During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle.
