Prometaphase Mitosis Prophase Telophase purple cell png Biology Diagrams Learn about the phases of mitosis and their significance in cell division on Khan Academy. Learn about the stages and mechanisms of mitosis, the process of nuclear division in eukaryotic cells. See diagrams of chromosome condensation, spindle formation, and kinetochore attachment.
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.

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. Figure 6.4 Animal cell mitosis is divided into five stages—prophase, prometaphase, metaphase, anaphase, and telophase—visualized here by light microscopy with fluorescence. Mitosis is usually accompanied by cytokinesis, shown here by a transmission electron microscope. (credit "diagrams": modification of work by Mariana Ruiz Villareal; credit "mitosis micrographs": modification of work by 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.
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. 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.
