Gap 1 (G1): cell individually grows

Synthesis (S): replicates its DNA

Gap 2 (G2): cell grows more in preparation for mitosis

# data[].attributes.body
Make sure the cell is growing well

Replicating its DNA correctly

Doing everything correctly before cells divide

# data[].attributes.body
Cells are not dividing most of the time

# data[].attributes.body
- Cells spend most time in interphase

# data[].attributes.body
- Cells divide to make more cells

# data[].attributes.body
Mitosis

Cytokinesis

# data[].attributes.body
Might not be able to communicate with other healthy cells

May not be able to carry out normal cell functions

May not securely anchor themselves

Lost control over their cell cycle

# data[].attributes.body
Genetic factors

Exposure to toxins, radiation

Excessive exposure to UV light

# data[].attributes.body
Cancer cells don't stop when they touch nearby cells, which keeps growing

# data[].attributes.body
Can spread to new places (metastasis)

# data[].attributes.body
Cells that divide too frequently (uncontrolled)

# data[].attributes.body
Independent assortment

Crossing over

Random fertilzation

# data[].attributes.body
Haploid sperm + haploid egg = diploid zygote

# data[].attributes.body
Sperm cells are not identical to the original cells and each other = creates variety

# data[].attributes.body
1. P2: Nuclear envelope breaks down

2. M2: Chromosomes line up in a single file

3. A2: Chromatids are pulled away

4. T2: Nuclei reforms into 4 cells

# data[].attributes.body
One diploid cell produces four haploid cells

# data[].attributes.body
Cytokinesis: Cytoplasm is split

# data[].attributes.body
Homologous chromosomes: chromosomes that are approximately the same size

# data[].attributes.body
1. P1: Chromosomes condense and thicken, crossing over happens

2. M1: Chromosome pairs line up in the middle of the cell

3. A1: Chromosomes are being pulled away

4. T1: Two nuclei are formed

# data[].attributes.body
Divides twice

# data[].attributes.body
Only divides once

# data[].attributes.body
- happens before mitosis and meiosis starts

# data[].attributes.body
Reduction division (46 chromosomes to 23)

# data[].attributes.body
Human sperm and egg cells have 23 chromosomes

# data[].attributes.body
A type of cell division by which sperm and egg cells (gametes) are produced

# data[].attributes.body
A process that contributes to genetic variety

# data[].attributes.body
Cytokinesis: Splits the cytoplasm into 2 new cells

# data[].attributes.body
1. Prophase: DNA forming into chromosomes

2. Metaphase: Chromosomes align in centre of cell

3. Anaphase: Chromosomes being pulled to opposite sides

4. Telophase: Cell beginning to split into two

# data[].attributes.body
Chromosomes are duplicated in interphase before mitosis and meiosis starts

# data[].attributes.body
Chromosomes are made up of long strands of DNA and protein

# data[].attributes.body
Chromosomes are found in the nucleus

# data[].attributes.body
Humans have 46 chromosomes (92 chromatids)

# data[].attributes.body
Divides and makes more cells

# data[].attributes.body
-  longest part of the cell cycle

# data[].attributes.body
Growth

DNA replication

Cell functions

# data[].attributes.body
Makes identical cells

# data[].attributes.body
Produces diploid somatic cells

# data[].attributes.body
A type of cell division done by most body cells

# data[].attributes.body
Helps with growth and repairs damaged and old cells
