10
The process by which the nucleus of a cell is divided into 2 identical sets each with the same number of chromosomes.
11
Mitosis
12
What type of cells undergo Mitosis?
13
Somatic Cells Or Body Cells
14
How many phases are there to Mitosis and what are they?
15
4 and they are Prophase, Metaphase, Anaphase, and Telophase.
16
What is the name of the protein disk that in Metaphase the spindle fibers attach?
17
Centromere
18
Chalones are a substance that prevent or inhibit mitosis. If you cut your finger what would your skin do increase or decrease the amount of chalones?
19
Decrease
20
This is a special kind of cell division where the number of chromosomes are cut in half?
21
Meiosis
22
A cell that has 23 chromosomes is called (hint: n)
23
Haploid
24
In meiosis the process starts with a diploid cell and ends with what?
25
4 Haploid
26
How many divisions of Meiosis are there and what are they called?
27
2, Meiosis I & Meiosis II
28
The exchange of genetic material in prophase I is called?
29
Cross Over
30
These are rod shaped structures that form during cell division.
31
Chromosome
32
The structure that holds two chromatids together.
33
Centromere
34
What makes up a chromosome?
35
2 Chromatids

How many chromosomes are in a Somatic Cell
37
46 total or 23 Pairs
38
Two copies of each chromosome that are similar in shape, size, and similar in genetic information are called what?
39
Homologous Chromosomes
40

44
The phase where the chromosomes line up is called what?
45
Metaphase
46
What is the last phase of Mitosis and Meiosis I & II
47
Telophase
48
Which phase does crossover occur?
49
Prophase I
50
What are the two processes by which cells divide.
51
Mitosis & Meiosis
52
How many eggs are made in Meiosis?
