What is the period of cell division during the cell cycle?
Mitosis
What kind of cells undergo Mitosis?
body cells
How many cell divisions happen during Meiosis?
2
Compared to mitosis, meiosis produces cells with ______ the number of chromosomes.
Half
Spindle fibers attach to the structure on the chromosome called what?
Centromere
What is the order of THE WHOLE cell cycle?
I-PMAT-C
How many daughter cells are produced at the end of Meiosis?
4
The body cell of a cat contains 38 chromosomes. How many chromosomes would a gamete have?
19
The part of the cell that disappears during Mitosis
Nucleus
What happens during Prophase?
Nuclei break down, DNA coils
What is the purpose of Meiosis?
Reproduction
A cell is in Prophase, and has 20 chromosomes. How many chromatids does it have?
40 (During Prophase, the DNA is already duplicated)
Genes are made up of what?
DNA
How many times do cells divide in Mitosis?
Once
4, unique
After cells are fertilized (two gametes combine to make a cell with 46 chromosomes), what kind of cell division will it go through?
What is the process that takes place during Meiosis that leads to genetic variety?
Crossing Over
What is the difference between Telophase and Cytokinesis?
Telophase is where the cells start to form (Nuclei reform, chromatin uncoils)
Cytokinesis is when the cells completely split
How many chromosomes do human gametes have? Why?
23
23+23=46
During prophase I, a cell has 16 chromaTIDS. After going through meiosis, how many chromaTIDS will it have?
4
(Divide twice. 16/2=8, 8/2=4)
