Prometaphase Diagram Biology Diagrams Provide mitosis diagrams for the stages of mitosis; Give you five resources for learning more about the phases of mitosis; Now, let's dive in! After prometaphase ends, metaphase—the second official phase of mitosis—begins. (Kelvinsong/Wikimedia Commons) Phase 2: Metaphase.
Prometaphase Figure %: Prometaphase The major event marking a cell's entry to prometaphase is the breakdown of the nuclear envelope into small vesicles. Kinetochores also become fully matured on the centromeres of the chromosomes. The disruption of the nuclear envelope allows for the mitotic spindles to gain access to the mature kinetochores. Prometaphase is a phase of mitosis in eukaryotic cells where the nuclear membrane breaks and the chromosomes form kinetochores. The kinetochore microtubules attach to the kinetochores and the chromosomes move to the centre of the cell.

Prometaphase is the second phase of mitosis, when the nuclear envelope breaks down and kinetochore microtubules attach to the sister chromatids. Learn more about the process and see a diagram of prometaphase at Scitable, a science learning platform. This diagram provides a visual representation of the different phases and helps in comprehending the complex process. It also enables scientists and students to identify and recognize the key features associated with each stage. The stages of mitosis include prophase, prometaphase, metaphase, anaphase, and telophase. The mitosis stages diagram provides a visual representation of the sequential phases of mitosis: prophase, prometaphase, metaphase, anaphase, and telophase. Each stage is characterized by distinct changes in chromatin organization, nuclear envelope breakdown, chromosome alignment, and spindle fiber formation.
