Mitosis results in the production of two genetically identical diploid cells. Meiosis produces for genetically different haploid cells. WitrynaAnaphase is the fourth step in mitosis. In anaphase, cohesin proteins binding the sister chromatids together break down. sister chromatids (now called chromosomes) are pulled toward opposite poles. What process occurs during anaphase 1?
