7. Brain Pop: Mitosis

8. 15R 9/6/11 OQC Notes: Brainpop-- Mitosis 1. When a cell divides, the nucleus leads the way. 2. We call it mitosis when the nucleus divides into two identical nuclei. 3. Each cell offspring will have a complete set of chromosomes. 4. Chromosomes are two DNA molecules held together by a centromere. 5. Every human cell has 46 chromosomes in all. 6. Mitosis has 4 steps: prophase, metaphase, anaphase, and telophase. 7. After mitosis, the cell membrane splits and TWO whole new cells are formed. 8. Both plant and animal cells do mitosis. 9. Organisms grow by cell division. Pair/Share (A with B and C with D)  “What is mitosis? What does it make?”
