Weba. Microtubules from the spindle poles attach to the kinetochores on the chromosomes. b. In anaphase, the spindle separates sister chromatids and pulls them apart. c. In metaphase, spindle microtubules align the chromosomes at the spindle midpoint. d. Cytokinesis describes the movement of chromosomes. e. WebThe centromere of each chromosome splits, and the two sister chromatids are pulled to opposite poles of the cell by the mitotic spindle. This is facilitated by the hydrolysis of a protein called cohesin, which holds the sister chromatids together. Finally, in telophase, the fourth and final stage of mitosis, the two daughter cells are formed.

WebThe S phase, short for synthesis phase, is a period in the cell cycle during interphase, between G1 phase and the G2 phase. Following G1, the cell enters the S stage, when DNA synthesis or replication occurs. At the beginning of the S stage, each chromosome is composed of one coiled DNA double helix molecule, which is called a chromatid.
