Cell Division

• Cell division is the process in which the cell divides.
• CHROMOSOMES contains DNA, RNA (Ribonucleic acid), and a number

  of proteins.
• DNA (Deoxyribonucleic acid) are materials that stores coded information about how an organism grows and develops.
• Human beings have 22 pairs of body chromosomes and 1 pair of

  sex cells chromosomes.
• The pair of sex chromosomes is represented by the letter X and y.
• MITOSIS Is a process in which the cell nucleus divides.

  It has four main stages.
• Mitosis has 4 main stages; Prophase, Metaphase, Anaphase, and Telophase.
• INTERPHASE is the period of cell growth, when the cell makes new molecules and

  organelles.
• PROPHASE is the first stage of mitosis, during which duplicated chromosomes

  condense to form structures visible with a light microscope. The mitotic spindle

  forms and begins moving the chromosomes toward the center of the cell.
• METAPHASE is the second stage of mitosis, all the cell’s duplicated chromosomes

  are lined up between the poles of the mitotic spindle.
• ANAPHASE is the third stage of mitosis, twin chromosomes split apart and move to

  opposite end of the cell.
• TELOPHASE is the fourth and final stage, during which daughter nuclei are formed

  at the two poles of a cell.
• CYTOKINESIS is the division of cytoplasm to form two separate daughter cells.
