mitosis

• Mitosis


  A type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus
• Prophase


  The first stage of mitosis where chromatin condenses, the nuclear envelope breaks down, spindle fibers form, and chromosomes align
• Chromatin


  The complex of DNA and proteins that makes up the chromosome
• Chromosomes

  The visible structures that form when chromatin condenses during prophase
• Spindle fibers

  The microtubules that form during prophase and attach to the centromeres to separate the chromosomes
• Centromeres

  The specialized regions on the chromosomes where the spindle fibers attach
• Microtubules


  Part of the spindle fibers that attach to the kinetochore, pulling chromatids apart during anaphase.
• Chromatid


  A single copy of a chromosome, consisting of a centromere and two sister chromatids.
• Kinetochore

  A protein structure that forms on each chromosome during mitosis, attaching to microtubules to pull chromatids apart.
• Anaphase


  The third stage of mitosis, where sister chromatids separate and move to opposite poles, with kinetochore attachment to microtubules.
• Mitosis

  A type of cell division that results in two daughter cells with the same number of chromosomes as the parent cell.
• Prometaphase


  The second stage of mitosis, where the nuclear envelope breaks down, kinetochore forms, and chromosomes start to decondense.
