WebbIn general, mitosis occurs through several stages that include: Prophase (divided into prophase and prometaphase) Metaphase. Anaphase. Telophase. Because of the rapid rate at which onion root tips grow as a result of rapid cell division, it's possible to observe and identify the different stages of mitosis. Webb11 juni 2024 · Prophase is the first stage of mitosis; the very first step in this crucial process of the M-phase of the cell cycle.Now as we all know that cell divisions are also of two types namely mitosis and meiosis, we shall learn in the following sections about prophase – mitosis, prophase 1 – meiosis, and prophase II – meiosis.Let’s move ahead …

WebbThe key event in prometaphase I is the attachment of the spindle fiber microtubules to the kinetochore proteins at the centromeres. Kinetochore proteins are multiprotein complexes that bind the centromeres of a chromosome to the microtubules of the mitotic spindle.
