WebLike mitosis, meiosis also has distinct stages called prophase, metaphase, anaphase, and telophase. A key difference, however, is that during meiosis, each of these phases occurs …

WebFeb 4, 2024 · The four stages of mitosis are known as prophase, metaphase, anaphase, telophase. Additionally, we’ll mention three other intermediary stages (interphase, prometaphase, and cytokinesis) that play a role in mitosis. During the four phases of mitosis, nuclear division occurs in order for one cell to split into two. Sounds simple enough, right? WebThe final stage of mitosis is telophase (Fig. 7).
