The following points highlight the four important phases of mitosis. The phases are: 1. Prophase 2. Metaphase 3. Anaphase 4. Telophase. Mitosis: Phase # 1. Prophase: During prophase, the individual chromosome appears in double threaded structure composed of two chromatids from the beginning. During this phase, the volume of the chromosomes too increases considerably and there is initiation of coiling [...]
The following points highlight the top eight events of molecular mechanism in m-phase. The events are: 1. Molecular Mechanism of Chromosome Condensation 2. Molecular Mechanism of Nuclear Membrane Breakdown 3. Molecular Mechanism of Spindle Formation 4. Molecular Mechanism of Capturing Chromosomes by Microtubules 5. Molecular Mechanism of Separation of Chromatids and Others. Events of Molecular Mechanism in M-Phase: Molecular Mechanism [...]
The below mentioned article provides a short note on Microtubule and Spindle. During the process of cell division the cytoplasmic network of microtubules disappears and the microtubules are reassembled in the form of spindle in the dividing cell (in both mitotic and meiotic cell division). Though the controlling pattern of this disappearance and recognized is not very clear, but it [...]
