100
Meiosis creates ____ genetical ___________ daughter cells.
4, different
100
The type of cell division that creates sperm and egg cells.
Meiosis
200
Failure of sister chromatids to separate during meiosis
Nondisjunction
200
DNA replication occurs in which stage of the cell cycle?
S phase (Interphase)
200
These exist at G1, G2, and M phase to make sure the cell is dividing properly
Checkpoints
200
A female squirrel's egg cell contains 20 chromosomes (n). How many chromosomes would her skin cell (2N) contain?
40
200
Starts with a diploid cell.
Both
300
The second stage of mitosis where chromosomes line up in the middle
Metaphase
300
Bacteria reproduce via binary fission which allows them to reproduce faster but have less genetic variation. This is what type of reproduction?
Asexual
300
True or False
Cancer cells have more numerous mutations, divide faster, and may spread through the body.
True
300
In humans how many chromosomes does each parent contribute to their offspring?
23
300
Number of chromosomes goes 2N to N.
Meiosis
400
Two identical copies of chromosome where spindle fibers attach
Sister Chromatid
400
A scientist looking at cells under a microscope would know that the cell is in the metaphase stage when what occurs?
The chromosomes line up in the middle.
400
What would happen to a person that was exposed to excessive radiation? (radiation is a carcinogen)
They would have an increased risk of cancer.
400
What stage of Meiosis is this?
Metaphase I
400
This is the cell division needed to fix a wounded knee.
Mitosis
500
Pair of matching chromosomes, with one inherited from each parent
Homologous Chromosomes

G1,S,G2,Prophase,Metaphase,Anaphase,Telophase, Cytokinesis
500
A cell may exit the cell cycle and enter into this new stage of life, where they no longer divide. This is what happens to brain tissue.
G0

What occurs during Prophase I of meiosis?
Crossing Over
500
Interphase occurs before the start of the process
Both
