  • Mitosis
    • Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells.
    • The word "mitosis" means "threads," and it refers to the threadlike appearance of chromosomes as the cell prepares to divide.
    • Early microscopists were the first to observe these structures, and they also noted the appearance of a specialized network of microtubules during mitosis. These tubules, collectively known as the spindle, extend from structures called centrosomes — with one centrosome located at each of the opposite ends, or poles, of a cell.
    • As mitosis progresses, the microtubules attach to the chromosomes, which have already duplicated their DNA and aligned across the center of the cell. The spindle tubules then shorten and move toward the poles of the cell.
    • As they move, they pull the one copy of each chromosome with them to opposite poles of the cell. This process ensures that each daughter cell will contain one exact copy of the parent cell DNA.
    • Mitosis consists of five morphologically distinct phases: prophase, prometaphase, metaphase, anaphase, and telophase.
      • Each phase involves characteristic steps in the process of chromosome alignment and separation. Once mitosis is complete, the entire cell divides in two by way of the process called cytokinesis




Only problem is that Im looking for a quick and easy mindmap including the necessary facts for mitosis for GCSE. Great mindmap though.
