Web22 mrt. 2024 · Stages Of Mitosis. The mitotic phase involves five phases: Prophase is the first stage of mitosis, throughout which the chromosomes and other nuclear contents start to condense into a thicker mass. But before this, there is a preprophase stage in which a preprophase band is formed beneath the plasma membrane. WebMitosis 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).
