Chromosomes reach the centrioles

WebMitotic errors could be explained by defects in embryo cleavage related to defective sperm centrosome or an abnormal number of male centrioles resulting in the formation of abnormal spindle, with an abnormal distribution of chromosomes among sister cells. 51–53 Aneuploidies could occur by different mechanisms such as premature cell division ...

What happens to centrioles during mitosis? – Wise-Answer

WebMar 15, 2024 · During mitosis or cell division, the centrosome and centrioles replicate and migrate to opposite ends of the cell. Centrioles help to arrange the microtubules that move chromosomes during cell division to ensure each daughter cell receives the appropriate number of chromosomes. What phase of mitosis do centrioles appear? WebSep 5, 2024 · The centrioles are present at opposite poles of the cells. Chromosomes are linked at the metaphase plate. During anaphase, sister chromatids are pulled towards the opposite poles. During telophase, the chromosomes are present at the opposite pole. The nuclear envelope surrounds each set of chromosomes.
