WebbDuring chromosome replication in interphase, the chromosomes are copied and later form a replicated chromosome with two identical sister chromatids. Those replicated, homologous chromosomes come together in prophase I to form a tetrad. Image by M. Hanneman, 2024. CC BY-NC-SA 4.0. Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase).
