Principles of Biology : Quiz 11 Study Guide


We will take Quiz 10 on Wednesday, November 5. I recommend that you answer these questions yourself or with classmates. This not a graded assignment, nothing is to be turned in. These questions are just to help you prepare for this quiz.
Reading: You should read Chapter 10, Section 10.7 (page 197) and all of  Chapter 11. This quiz will cover the basics of meiosis and a comparison with mitosis.

There are flashcards and animations on the Aris site you should study.   Quick Link to the Aris Site.

Questions to consider:

Cell Cycle and the Control of the Cell Cycle
1) What is meant by the term "cell cycle?"
2) What are the basic stages of the cell cycle?
3) What are the major three checkpoints of the cell cycle?
4) What do all cancers have in common?
5) What is the p53 gene? What role does the p53 protein play in the cell cycle?
6) What happens if a cell has a mutated p53 gene?
7) p53 is considered a "tumor-suppressor gene."  Explain.

Sexual Life Cycles - You should know the life cylce of each of the following:
You should be able to identify the haploid phase, the diploid phase, the process of mitosis and the process of meiosis. You should be able to apply the following terms: gamete, egg (ovum), sperm, zygote, blastula, gametophyte, sporophyte, fertilization, meiosis, mitosis, haploid cells (including spores) ... as appropriate.

Cell Division - Meiosis
8) What type of cell is theoretically capable of undergoing meiosis?
9) What type of cells actually do under go meiosis?
10) What is the typical result of meiosis?
11) What is meant by the terms haploid, diploid, and polyploid?

13) What are the stages of Meiosis II? Describe them.
14) What is "crossing over?" Where does it occur? When does it occur?
15) What is the effect of crossing over? That is, what does it matter?
16) Explain "The Alternation of Generations" as a generalized pattern which is found in all sexually reproducing species.
17) Describe and explain the major differences between mitosis and meiosis.
