Name that phase
The first phase of mitosis
What is, prophase
What is,
Stem cells
Cancer is uncontrolled _______ ________
What is, Cell division
During this phase, chromosomes line up in the center of the cell and spindle fibers attach to them.
What is, Metaphase
Another word for a Totipotent stem cell
What is, a Zygote
Term for something that has been shown to increase the chances of getting cancer
What is, carcinogen
These structures form during Prophase when chromatin condenses.
What is, chromosomes
Condensed genetic material seen beginning in prophase
What is, chromosome
3 reasons why an organism's cells might undergo mitosis:
What is
1- Growth of organism
2- Repair of tissue
3- Asexual Reproduction
What can adult stem cells specialize into?
What is, cells within their organ system
1) Term for a cancerous tumor: __________
2) Term for a non-cancerous tumor: __________
What is
1- malignant
2- benign
In this phase, new nuclear envelopes appear.
What is, telophase
Name of the protein that binds DNA in its coiled shape
What is, histones
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.
Why are Induced Pluripotent Stem cells considered to be more ethical?
Because they are not embryonic stem cells. Any cell can be induced into an IPS
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
