Name that phase
The first phase of mitosis
What is, prophase
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
Cancer is uncontrolled _______ ________
What is, Cell division
What is,
Stem cells
Term for something that has been shown to increase the chances of getting cancer
What is, carcinogen
Condensed genetic material seen beginning in prophase
What is, chromosome
What is it called when the cell's cytoplasm divides and the cell cleaves in two
What is, cytokinesis
Why would damage to your tissues lead to mitosis
What is,
cells must be replaced, therefore surrounding cells replicate to make up for it
1) Term for a cancerous tumor: __________
2) Term for a non-cancerous tumor: __________
What is
1- malignant
2- benign
In this phase, a new nuclear envelope appears.
What is, telophase
Name of the protein that binds DNA in its coiled shape
What is, histones
Name for the body cells that undergo mitosis
What is somatic cells
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.
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
This is the phase when helicase unwinds DNA strand and polymerase attaches identical bases to make two copies of the DNA
What is, interphase
Explain what happens to chromosomes during anaphase
What is, the sister chromatids are split apart and separated to each pole of the cell
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
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
