Hi folks,
Today we finished off 2019 by taking a look at meiosis. Meiosis is the process of cell division where the end product is a haploid cell that is genetically unique from the cells that it came from. When we get back from break we will begin our genetics unit.
We are off for the next two weeks so here wishing that everyone's holidays are merry, joyful, peaceful and safe!
For homework due 1/6
Do the enclosed .pdf (Answers included in the email)
Answer the following questions based on today's meiosis and mitosis simulation. Answers also included. (STUDY THEM! :) )
1. What did the little pickle shaped pieces of paper represent?
2. Why were there two different colors of paper?
3. To illustrate DNA synthesis, what did we do?
4. What represented the sister chromatids?
5. What represented homologous chromosomes?
6. What did the tape represent when we taped the two pieces of paper together?
7. In mitosis, when you illustrated metaphase, how were the papers lined up?
8. In meiosis, when you illustrated metaphase I, how were the papers lined up?
9. During meiosis prophase I, what did you do to show the tetrads?
10. What did you do to illustrate "crossing over" in meiosis prophase I.
11. To illustrate anaphase I in meiosis, what did you do to your little sister chromatids? Careful here.
12. To illustrate anaphase II in meiosis, what did you do to your little sister chromatids.
13. How were your sister chromatids lined up in meiosis, metaphase II?
14. What did you do to illustrate independent assortment?
15. What are the two ways that genetic shuffling takes place in meiosis?
16. In what phases do those two types of shuffling take place in meiosis?
17. When we started, how many chromatids were in the cell we worked with today?
18. After synthesis, how many chromatids were in the cell we worked with today?
19. After synthesis, how many CHROMOSOMES were in the cell we worked with today?
20. When we finished mitosis, how many chromosomes did the finished cells have?
21. When we finished mitosis were the cells diploid or haploid?
22. When we finished meiosis, how many chromosomes did the finished cells have?
23. When we finished mitosis, how many cells did we end up with?
24. When we finished meiosis, were the cells diploid or haploid?
25. When we finished meiosis, how many cells did we end up with.
26. Why is an enzyme called a catalyst?
