G1- Grow S- Syntesis G2- Grow again
100
What are the four stages of mitosis
Prophase Metaphase Anaphase Telophase

What is cancer?
a disorder in which body cells lose the ability to control growth
100
What is the concern for skin cancer?
That it will spread to other parts of the body.

DNA is found in the.. 

chromatin inside the nucleus.

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

A DNA molecule looks like a twisted ladder, which is made up of units called ..... 

nucleotides.

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

Each nucleotide is made up of 3 components: 


A 5-carbon sugar called Deoxyribose.

Phosphate group which make up the “sides” of the ladder.

Nitrogen base which make up the “rungs” of the ladder.

Why do cells divide?

Cells need to divide for your body to grow and for body tissue such as skin to continuously renew itself.

400
What is Cytokinesis
Cytokinesis- divids the cytoplasm for two identical cells
400
This is the study of cancer
Oncology

Cell suicide is known as?
apoptosis

DNA has four kinds of nitrogen bases:

adenine, thymine, guanine, and cytosine
