Movement of chromosomes in cell division

Nettet9. apr. 2024 · The two centrosomes will give rise to the mitotic spindle, the apparatus that orchestrates the movement of chromosomes during mitosis. At the center of each animal cell, the centrosomes of animal cells are associated with a pair of rod-like objects, the centrioles, which are at right angles to each other. Centrioles help organize cell division. Nettet25. mar. 2024 · Chromosomes carry genetic information in a molecule called DNA.

Chromosome Movement during Cell Division - Biology …

NettetOption E: ∙ The chromosomes move toward opposite poles during cell division immediately after their centromere splits. ∙ Spindle fibers get attached with the kinetochores of the chromosome and pull the centromere toward opposite direction. Thus, the chromosomes get separated. ∙ This happens in anaphase of the cell cycle.
