Question
This is the correct order of steps of mitosis.
Answer
What is prophase, metaphase, anaphase, and
telophase (PMAT)?
Question
This is the longest phase of the cell cycle.
Answer
What is interphase?
Question
After cells divide, they re-enter the G1 step to get
ready to divide again or they can enter this step to
rest.
Answer
What is G0?
Question
The “restriction check point” occurs in this part of
the cell cycle.
Answer
What is at the G1 phase?
Question
When this gene’s functions are turned off, cells
begin to pass division checkpoints with damaged
DNA which leads to cancer.
Answer
What is the p53 gene?
Category 2 questions follow
Question
These types of cells will never regenerate if they are
damaged.
Answer
What are muscle and nerve cells?
Question
The three major checkpoints of the cell cycle occur
at these steps.
Answer
What is G1, G2, and M?
Question
These cells divide once every 1 to 2 years.
Answer
What are liver cells?
Question
These regulatory proteins fluctuate in concentration
throughout the cell cycle.
Answer
What are cyclins?
Question
This forms when cyclins and cdk’s unite in the cell
cycle.
Answer
What is the MPF complex? (Mitosis Promoting
Factor)

Question
These are the correct steps of the signal
transduction pathway.
Answer
What is reception, transduction, and response?
Question
A ligand binding to a receptor is very similar to this
other analogy in biology because of its specificity.
Answer
What is a substrate binding to an enzyme?
Question
When tyrosine kinases are bound by 2 ligands, they
join together forming this.
Answer
What is a dimer?
Question
These are two examples of steroid hormones that
pass easily through the cell membrane to bind to
intracellular receptors to initiate a response in the
nucleus for transcription.
Answer
What is testosterone and estrogen?
Question
This is the type of energy required for G-proteins to
function.
Answer
What is GTP?
Category 4 questions follow
Question
This type of cell signaling involves self-signaling in
the same cell.
Answer
What is autocrine?
Question
Plant cells are able to perform juxtacrine signaling
with other cells through these special features in
plant cells.
Answer
What is a plasmodesmata?
Question
This type of signaling involves hormones and
requires traveling great distances through blood
vessels.
Answer
What is endocrine?
Question
cAMP, cGMP, calcium ions, and IP3 all have this main
similarity.
Answer
What is being secondary messengers?
Question
This secondary messenger binds to calcium channels
in the endoplasmic reticulum to open the channel.
Answer
What is IP3?
Category 5 questions follow
Question
These form on the outside of centromeres and allow
for spindle fiber attachment.
Answer
What are kinetochores?
Question
Crowded cells stop dividing because of this growth
factor.
Answer
What is density-dependent inhibition?
Question
This term describes the fact that cancer cells may
spread to other locations of the body.
Answer
What is metastasis?
Question
During telophase/cytokinesis, these are to main
differences between plant and animal cells.
Answer
What are cleavage furrows and cell plates?
Question
This enzyme is responsible for deactivating protein
kinases by removing a phosphate group.
Answer
What is protein phosphatase?
