MITOSIS

• Cell Division - Takes place in all types of cell and is responsible for the formation of new cells.
• Cell division - Begins when the parent cell divides and forms daughter cells.
• Interphase - Is the preparation time that a cell undergoes before it divides
• A cell in the interphase will experience the following: increase in the number of organelles, increase in size, and most importantly, the replication of DNA.
• Interphase is a part of the cell cycle checkpoint that directs a cell when to proceed or to stop dividing.
• The G1 phase is where the cell grows and prepares itself for mitosis by synthesizing proteins needed during mitosis.
• Mitosis - A type of cell division that produces 2 diploid daughter cells from a single parent cell.
• Mitosis - A type of cell division that produces 2 diploid daughter cells from a single parent cell.
• Diploid means there is a double chromosome in a cell.
• Mitosis occurs in somatic or body cells
• Prophase – sister chromatids of the cells are now formed. They are joined in the center by the circular structure called a centromere. The centrioles are doubled and continue to move in opposite directions
• In Prophase, the nuclear envelope is still disintegrating or breaking apart.
• Metaphase – nuclear envelope is no longer present. The chromatids are now in the center or metaphase plate. The centrioles are now at opposite poles. The spindle fibers attach themselves to the chromosomes by the kinetochore.
• Anaphase - chromosomes are divided into 2 parts, being pulled by the spindle fibers moving towards the opposite poles. A cleavage furrow is now visible as a result of the cell pulling away from each other.
• Telophase – has 2 stages. The first one is karyokinesis or the full separation of chromosomes and the nucleus forms for each cell. The other stage is cytokinesis. This time, the cell is now separated and no more cleavage is present
