During the next stage of meiosis, called Prophase I, chromosomes with similar sequences form pairs and undergo recombination, creating physical links that hold the homologs together. WebThe sister chromatids are still tightly attached to each other. At this time, the chromosomes are maximally condensed. During anaphase, the sister chromatids at the equatorial plane are split apart at the centromere.

The sister chromatids separate from one another and are pulled towards opposite poles of the cell. The microtubules that are not attached to chromosomes push the two poles of the spindle apart, while the kinetochore microtubules pull the chromosomes towards the poles. grants white goods

A sister chromatid refers to the identical copies (chromatids) formed by the DNA replication of a chromosome, with both copies joined together by a common centromere.

WebThe sister chromatids are still tightly attached to each other by cohesin proteins. At this time, the chromosomes are maximally condensed. Anaphase. During anaphase, the cohesin proteins degrade, and the sister chromatids separate at the centromere. WebEventually, all the sister chromatids will be attached via their kinetochores to microtubules from opposing poles. Spindle microtubules that do not engage the chromosomes are called polar microtubules. These microtubules overlap each other midway between the two poles and contribute to cell elongation.
