Web4. Anaphase: The sister chromatids are then pulled apart by the mitotic spindle which pulls one chromatid to one pole and the other chromatid to the opposite pole. 5. Telophase: At each pole of the cell a full set of chromosomes gather together. A membrane forms around each set of chromosomes to create two new nuclei. WebApr 10, 2024 · A stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second-most condensed and coiled stage is known as metaphase. Carrying genetic information, aligned in the equator of the cell before being separated into each of the two daughter cells is being done with these chromosomes.

WebThe first of these, anaphase A, moves chromosomes to either pole of a dividing cell (marked by centrosomes, from which mitotic microtubules are generated and organised).
