Web3 jun. 2024 · Both mitosis and meiosis are comprised of chronological phases: (1) prophase, (2) metaphase, (3) anaphase, and (4) telophase. Since meiosis is comprised of first and second meiotic divisions, these phases occur twice, each designated as I and II. WebThe mitotic checkpoint prevents the metaphase–anaphase transition by inhibiting the degradation of cyclin B and securin. Cyclin B is a Cdk1 regulatory subunit that is needed to drive mitosis [52] , whereas securin is a repressor of separase, an enzyme that hydrolyzes RAD21, a subunit of the cohesin complex that holds sister chromatids together [53] .
