STUDY GUIDE
LAB 5: Mitosis, Meiosis
Most answers can be pulled out from your lab manual and results obtained during the lab. For some concepts, you
might need to check your book or Google the definition online!
MITOSIS
1. Explain the different parts of the cell cycle and what happens in each one: Interphase (G1, S, G2 ), Mitosis, and
Citokinesis
2. What is the main purpose of a mitotic cell division?
3. List the three main reason why mitotic cell division is needed in your body
4. When is the DNA actually replicated (duplicated) during the cell cycle
5. What is the difference between cytokinesis and mitosis?
6. List the four stages of mitosis (Prophase, Metaphase, Anaphase, Telophase) and explain what allows you to
differentiate each one when the cell is dividing
7. How can you tell the difference between a cell in interphase and one in cell division?
8. What stage of mitosis is closer to cytokinesis?
9. How is cytokinesis in plant cells different from that of animal cells? What is responsible for those differences?
10. How many total chromosomes and DNA molecules would be found in human somatic cell in G1?
11. How many total chromosomes and DNA molecules would be found in human somatic cell in G2?
12. How many daughter cells result from a mitotic cell division?
13. Are mitotic cells diploid or haploid?
14. Are they identical or different to other daughter cells?
MEIOSIS
15. What are the main differences between mitosis and meiosis?
16. Explain crossing over, when does it occur?
17. Explain Random (independent) assortment, when does it occur?
18. After cytokinesis I, how many daughter cells are produced? Are these cells diploid or haploid?
19. After cytokinesis II, how many daughter cells are produced? Are these cells diploid or haploid?
20. Does DNA synthesis takes place before meiosis 1, meiosis 2, or both?
21. How many total chromosomes and DNA molecules would be found in human meiotic cell in G1 of meiosis 1?
22. How many total chromosomes and DNA molecules would be found in human meiotic cell in G2 of meiosis 1?
23. How many total chromosomes and DNA molecules would be found in human meiotic cell in G1 of meiosis 2?
24. How many total chromosomes and DNA molecules would be found in human meiotic cell in G2 of meiosis 2?
25. How many total chromosomes and DNA molecules would be found in human somatic cell in G2?
26. Are daughter identical or different to other daughter cells after meiosis?
