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? Anaphase I is the third stage of meiosis I and follows prophase I and metaphase I. This stage is ...
