The first phase of mitosis

What is, prophase

100
Long, thin fibers of DNA and proteins
What is, chromatin
100
The cell cycle results in two genetically _________ cells.
What is, Identical

4 reasons why an organism's cells might undergo mitosis:

What is

1- Growth of organism

2- Repair of tissue

3- Asexual Reproduction

4- Cell specialization

100

Cancer is uncontrolled _______   ________

What is, Cell division

200
During this phase, chromosomes line up in the center of the cell and spindle fibers attach to the centromeres.
What is, Metaphase
200
One half of a duplicated chromosome
What is, sister chromatid
200
What is the longest phase in the cell cycle?
What is, Interphase
200
Cells responsible for specializing their daughter cells:

What is,

Stem cells

200

Term for something that has been shown to increase the chances of getting cancer

What is, carcinogen

300
These form during Prophase when chromatin condenses.
What is, chromosomes
300

Condensed genetic material seen beginning in prophase

What is, chromosome

300

What is it called when the cell's cytoplasm divides and the cell cleaves in two

What is, cytokinesis

300

Why would damage to your tissues lead to mitosis

What is,

cells must be replaced, therefore surrounding cells replicate to make up for it

300

1) Term for a cancerous tumor: __________

2) Term for a non-cancerous tumor: __________

What is

1- malignant

2- benign

400

In this phase, a new nuclear envelope appears.

What is, telophase

400

Name of the protein that binds DNA in its coiled shape

What is, histones

400

Name for the body cells that undergo mitosis

What is somatic cells

400

Explain why mitosis is the primary mechanism for asexual reproduction

Because it results in genetically identical cells. Asexual reproduction is a form of cloning oneself.

400

Explain how mitosis checkpoints may lead to cancer

What is:

Checkpoints are maintained by proteins that may have been mutated and can no longer ensure that a cell can exit mitosis. In that case the cell continues to divide indefinitely 

500

This is the phase when helicase unwinds DNA strand and polymerase attaches identical bases to make two copies of the DNA

What is, interphase

500

Explain what happens to chromosomes during anaphase

What is, the sister chromatids are split apart and separated to each pole of the cell

500

Why must reproductive cells undergo a different type of cell division?

What is: reproductive cells need to have 1/2 the number of chromosomes, so they can form a new individual by combining with another reproductive cell

500

How are specialized cells genetically different from one another; i.e. how is a muscle cell and a nerve cell genetically different?

What is, they are not! They have different genes activated, and express those genes differently

1- Most common cancer in men: ___________

2- Most common cancer in women: ___________

What is,

1- Prostate

2- Breast
