This is the repeating sequence of growth and division in the life of a cell
cell cycle 
100
This process makes IDENTICAL cells
mitosis 
100
This is the process that makes more skin cells
MITOSIS!
100
Humans have _______ chromosomes in somatic (body) cells.
46
100
Humans have ______ chromosomes in gametes
23
200
What is MADE during the S phase of the cell cycle?
DNA is replicated (copied) 
200
Is MITOSIS sexual or asexual reproduction?
asexual 
200
AFTER a zygote is formed, what process makes more cells?
Mitosis 
200
This is a picture of the chromosomes in a cell. You can tell if the person is missing a chromosome or has an extra chromosome and if the person is a male or female.
karyotype
200
An egg and sperm come together in this process
fertilization 
300
What THREE parts of the cell cycle are collectively known as INTERPHASE?
G1, S, G2
300
During this phase of MITOSIS, chromosomes line up in the MIDDLE of the cell.
Metaphase
300

This is when portions of a chromatid on one homologous chromosome break off and trade places with the corresponding portion on one of the chromatids of the other homologous chromosome


crossing over
300

A elephant has 56 chromosomes in its somatic cells. How many chromosomes would be in a cell produced by MITOSIS?

56
300
What TWO cells combine to form a zygote?
egg and sperm (gametes)
400
What are HOMOLOGOUS CHROMOSOMES?
Chromosomes that are similar in size, shape, and genetic content. 
400
List the ORDER of the phases of MITOSIS
Prophase, Metaphase, Anaphase, Telophase
400
This process forms HAPLOID cells
meiosis 
400
A elephant has 56 chromosomes in its somatic cells. How many chromosomes are in its gametes?
28
400
Define ZYGOTE
The first cell; a fertilized egg

What is ONE reason normal cells can become cancer cells 

1. regulation of cell growth and division is lost.

2. cells continue to divide without passing through G1

3. cells do not respond normally to control mechanisms - DNA repair enzymes (checkpoints) fails.





500
This is the random distribution of homologous chromosomes during meiosis. Leads to genetic variation
Independent Assortment 
500
List THREE differences between MITOSIS and MEIOSIS 
1. Mitosis- 2 cells, identical, diploid, 

2. Meiosis- 4 cells, crossing over (genetic variation), haploid 

500

A gamete will receive too many or too few homologues of a chromosome if THIS occurs during meiosis. This is why Down's Syndrome occurs

Nondisjunction. 
500
CONTRAST Haploid and Diploid
Haploid- 1 set of chromosomes (n); gametes

Diploid- 2 sets of chromsomes (2n); somatic cells
