WebThe chromosomes align themselves in a line spanning the cell. Microtubules, essentially miniature strings, splay out from opposite ends of the cell and shorten, pulling apart the sister chromatids of each chromosome. [4] As a matter of convention, each sister chromatid is now considered a chromosome, so they are renamed to sister … WebApr 8, 2024 · The alignment of the chromosomes, with sister chromatids on each side of the metaphase plate ensures the two new cells will be identical. The sister chromatids represent the two new strands of DNA created from one chromosome during the synthesis stage of interphase. How are homologous pairs attached to each other in meiosis?
