Name That Phase
Mitosis
Meiosis
Cancer
Random
100
Chromatids are pulled to the opposite poles of the cell and the nucleus begins to reform.
Telophase
100
Why is interphase the longest phase of the cell cycle?
This is where the cell grows and functions and where DNA is duplicated before it divides in either mitosis or meiosis.
100
What is different about the chromosomes in Prohpase I of meiosis in comparison to Prophase of mitosis?
In meiosis, crossing over occurs when like chromosomes pair up in tetrads.
100
Although there are several different types of cancer, what do they all have in common?
The cell cycle has been disrupted.
100
The ability of water molecules to stick to other water molecules
What is cohesion?
200
If a cell were cancerous, then this phase is most likely the one that has been interrupted.
Interphase.
200
This is the phase in which chromosomes line up in the middle of the cell.
Metaphase
200
How many times does a cell go through interphase during Meiosis I & II?
Interphase only happens ONCE!!
200
True or False. Cancer cells have contact inhibition, whereas when other cells get too close, they stop growing.
False. Cancer cells have no contact inhibitioin.
200
This property of water moderates temperature- this is why Florida is a great place to live ALL year long.
What is a high specific heat?
300
DNA is replicated
Interphase
300
This is the phase in which chromosomes condense and can be clearly seen with a microscope and spindle fibers begin to elongate.
What is Prophase?
300
If a the body cells of a gorilla contain 20 chromosomes, how many chromosomes would be in the gametes of a female gorilla?
10
300
These are proteins that regulate the timing of the cell cycle.
What are cyclins?
300
DNA is this type of macromolecule.
What is a nucleic acid?
400
Tetrads line up in the center of the cell.
Metaphase I
400
This is the phase in which chromatids are pulled apart due to the shortening of spindle fibers.
What is Anaphase?
400
What is the purpose of meiosis?
To create reproductive cells only.
400
Any substance that can damage DNA and cause cancer is known as a...
Carcinogen
400
The building blocks of proteins consist of these which are coded for once mRNA has been translated.
What are amino acids?
500
Crossing Over Occurs
Prophase I
500
This process is where the cytoplasm and organelles are divided among two cells that now have their own complete set of DNA.
What is cytokinesis?
500
The process of meiosis results in (1,2,4,6 ) (haploid/diploid) daughter cells with (double/the same/half) the amount of chromosomes.
4 haploid half
500
Name one factor that cause cancer?
Cigarette Smoke, Radiation, Chemicals, Viruses
