Storyboard Text
- Tiffany is frusrated because she didn't know what to with her assignment so she called her mom and ask for help
- ...
- Sure sweetie. I'll explain to you how meiosis happen
- Mom can you help me with my science homework? It's about the meiosis
- What is Meiosis?Meiosis is a process where a single cell divides twice to produce for cells containing half the original amount of genetic information. These cells are our sex cells -spermcell in male and eggcells in female.
- Phases of MeiosisProphase I - The chromosomes condense and the nuclear envelope breaks down. Crossing-over occurs.Metaphase I - Pairs of homologous chromosomes move to the equator of the cell
- Anaphase I - Homologous chromosomes move to the opposite poles of the cell.Telophase I Cytokenesis - Chromosomes gather at the polesof the cell. The cytoplasm divide. Prophase II- A new spidle forms around the chromosomes
- Metaphase II - Chromosomes line up at the equator.Anaphase II - Centromeres divide. Chromatids move to the opposite pole of the cells. Telophase II and Cytokenesis- A nuclear envelope forms around each set of chromosomes. The cytoplasm divide
- What is Meiosis?Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.
- and that is meiosis and its phases . Do you understand it already?
- Yes mom thank you. I can now finish my homeworks and watch movies afterwards.
