Mitosis and Cancer
What are the four stages of mitosis?
Prophase, Metaphase, Anaphase, Telophase
What process increases genetic diversity in Meiosis? What phase does this occur in (make sure to include the I or II after)?
1. Increases genetic diversity in a cell . 2. It happens during prophase I
What is the difference between haploid and diploid?
Haploid has one set of chromosomes (n). Diploid has two sets of chromosomes (2n)
What are the three parts of the cell cycle (in general whether is be mitosis or meiosis)
Interphase---> Cell Division -----> Cytokinesis.
What are the four macromolecules
Lipids, Carbohydrates, Proteins, Nucleic Acids
During Prophase:1. DNA turns into what during Prophase? 2. What disappears? 3. What begins to moves opposite sides of the cell?
1. DNA becomes chromosomes 2. Nuclear membrane and nucleolus 3. Centrioles
How many daughter cells do you get at the end of meiosis? Are those cells different or identical?
1. 4 daughter 2. Cells that are all different.
1. Asexual reproduction does what process? 2. Sexual Reproduction does which process? 3.Which one do you want if you want to produce GAMETES?
1 Mitosis 2.Meiosis . 3. Meiosis/Sexual
What are the three stages within Interphase?
G1, S, G2
When water sticks to water, this is ______________. When water sticks to a different substance, this is ___________.
Cohesion, Adhesion
Mitosis produces how many daughter cells? Are they different or identical?
2 daughter cells that are identical
Meiosis creates haploid cells. What does this mean?
The number of chromosomes are half of what the original cell had.
If you start cloning organisms, what will be lost? (Hint: crossing over does this)
Genetic diversity
What happens during the S phase of Interphase?
DNA replicates
Enzymes work by lowering the ____________.
Activation Energy
If something goes wrong during interphase, the cell is moved into what phase: G0, G1, or G3
G0
After meiosis I, before you begin meiosis II, you go through interphase again. True or False?
False
Embryonic stem cells are controversial because the fertilized egg must be destroyed. This type of controversial issue is considered to be an _____ issue.
Ethical
What is cytokinesis?
When the cytoplasm of both newly made cells physically separate from one another.
Whatever the cell makes that needs to be shipped off, goes to this organelle (which modifies and packages).
Golgi Apparatus/Golgi Bodies
Cancer is caused by uncontrolled cell growth. Which one would most likely cause cancer? Bacteria, Crossing Over, or Mutations (Changes in the DNA)?
Mutations
True or False? The number of CELLS produced by meiosis is twice the number of CELLS produced by mitosis
True
During mitosis, PMAT is completed _____ time, but in meiosis, PMAT is down __________ times.
One, Two
The cell spends most of its time in what phase of the cell cycle?
Interphase
What is the chemical formula for cellular respiration?
6O2 + C6H12O6 ------> ATP + 6H20 + 6CO2
