What cellular process forms egg and sperm cells?
Meiosis
100
What process is happening in the image?
Crossing over

From SpongeBob, What is Mr. Krabs' first name?
Eugene
100
What is cell differentiation?
the process by which cells become specialized in structure and function
100
What is cancer?
Disease caused by mutations in genes that control the cell cycle, leading to uncontrolled cell division.
200
What type of cell division is depicted below? Diploid # = 2.
Mitosis
200
What type of cells do mitosis
Somatic (body) cells
200
What is Mr. Martin's favorite kind of pen?
G2 Pilots
200
What makes stem cells so important?
They have not yet differentiated, so they have the potential to become anything.
200
What is the ultimate cause for cancer?
(do not name specific risk factors)
Mutations in the genes that control the cell cycle, leading to uncontrolled cell division.
300
What type of chromosome is #4?
Autosome
300
What cellular process allows an embryo to grow?
Mitosis
300
What happens when a cell can no longer control its rate of growth?
Cancer
300
What is the difference between adult stem cells and embryonic stem cells?
Embryonic stem cells can become anything, while adult stem cells are much more limited
300
What is the difference between a benign tumor and a malignant tumor?
400
What are the 4 major reasons for cell division?
Growth, efficient transport, repair/replacement, reproduction
400
How does meiosis contribute to genetic variation?
Meiosis creates a different daughter from each parent cell by doing crossing over and by making haploid cells
400
What is the word for "programmed cell death"?
Hint: it can make the cell "pop".
Apoptosis
400
Use an analogy to explain how gene expression causes cell differentiation.
Example:
Think of DNA as a complete cookbook with thousands of recipes. A liver cell reads only the 'liver recipes' while a muscle cell reads only the 'muscle recipes.' All cells have the FULL cookbook — they just use different pages!
400
What do the G1 and G2 checkpoints check for?
AND
What happens to a cell if it fails a checkpoint?
G1- nutrients, growth factors, DNA spellcheck
G2- size, DNA spellcheck again
If fail- Waits until it is ready/fixed or self destructs if damage is too severe.

What is the name of this disorder?
Monosomy X (Turner Syndrome)

Who wrote the original Jurassic Park book?
Michael Crichton

All of your body cells have all the same DNA, but your different cells all have completely different structures and functions...... how/why?
Gene expression: Only certain genes are used in each type of cell, and all the rest are turned off.

Name 5 things you can do to help protect yourself from cancer risk?
Genetic screening, avoid known carcinogens, use sunscreen / limit sun exposure, get vaccines, exercise / good diet, get checked by doctor regularly
