WebDec 30, 2024 · As the chromosomes approach the center of the mitotic spindle, the rate of microtubule shortening/lengthening slows. The sister chromatids are pushed and pulled … WebDuring prophase I, homologous chromosomes pair up and exchange sections of DNA. This is called recombination or crossing over. This is followed by metaphase I where the connected pairs of chromosomes …
WebApr 9, 2024 · The chromosomes are bound tightly together and in perfect alignment by a protein lattice called a synaptonemal complex and by cohesin proteins at the centromere. Located at intervals along the synaptonemal complex are large protein assemblies called recombination nodules. Web• Once crossing over is finished, homologous pairs align along midline of the cell randomly. • The homologous chromosomes then separate and move to opposite poles this results in the random assortment of paternal and maternal chromosomes, and their alleles (gene variants) in the gametes.
