What are the sub phases of interphase and what happens in each?
G1- Grow S- Syntesis G2- Grow again
100
What are the four stages of mitosis
Prophase Metaphase Anaphase Telophase
100
What is cancer?
a disorder in which body cells lose the ability to control growth
100

What is it called when a tumor stops growing?

Benign tumor

100

What happens when a cell is in G0 phase

non-dividing phase

200
Which phase lasts the longest; interphase, mitosis, or cytokinesis?
Interphase
200
Discribe four things that happen during prophase
1. nuclear envelope disappears 2. chromosomes thicken and become visible 3. centrioles start to move to opposite ends 4. spindle fibers begin to form
200
Name 3 causes of cancer
environmental-chemicals: cigarettes, asbestos. nitrates, pesticides, radiation, viruses, obesity/poor diet, defected gene.
200
Name the two types of tumors
benign tumor, malignant tumor
200

Which checkpoint ensures that the spindle fibers are attached correctly to the centromeres?

M

300
What is the job of a check point?
A check point is a stop along the cell cycle to make sure there are no mutations
300
In what stage does sister chromotids separate?
Anaphase
300
Why are cancer cells different
Don’t respond to signals and divide uncontrollably.
300
Which type of tumor is cancerous
malignant
300

What Checkpoint ensures that DNA has been copied correctly?

G2

400

Why do cells divide (3 reasons)?

Growth, Repair, Reproduction (in bacteria), and Replace old cells.

400
What is Cytokinesis
Cytokinesis- divids the cytoplasm for two identical cells
400
This is the study of cancer
Oncology
400
Cell suicide is known as?
apoptosis
400

What are cancer causing chemicals called?

Carcinogens
500
During which phase of the cell cycle would you expect the amount of DNA to change?
S phase
500
What is the result of Mitosis
A production of 2 new daughter cells that are identical to the parents cells
500
Cancer cells form a mass called what?
Tumor
500

A great number of cancer cells have a defect in something called p53 in their DNA. What does this refer to?

a gene

500

Name 3 ways that Mitosis is different than Meiosis

Mitosis - 1 division to produce 2 identical cells, diploid to diploid. Meiosis is two divisions to produce 4 haploid daughter cells (recombinant bc crossing over) from a diploid parental cell.
