When considering the stages of the cell cycle, which stage is best associated with
cells that do not divide, such as nerve cells?
G1 phase
M phase
O None - all cells divide
S phase
G2 phase
GO phase
Pickles are often preserved in a 20-30% salt solution called brine. How does brine
prevent contamination by microorganisms?
Bacteria can't survive in hypotonic solutions because of the added pressure of
the water they take in causing them to burst.
O Bacteria can't survive in a hypertonic solution because they lose too much water
and die.
O The high salt concentration increases the pH of the environment, making it
unfavorable for bacteria to live there.
The high salt concentration creates an isotonic environment that the bacteria
cannot live in.
Bacteria cells are unable to digest the salt, thus killing the cells by starvation.
Which one of the following statements best describes the mechanism by which the
"cell cycle control system" regulates events of the cell cycle?
O Hydrophobic signaling molecules cross the plasma membrane at distinct stages in the cell
cycle
O Ca++ and CAMP release into the nucleus signal the progression of the cell cycle
Changes in vesicle trafficking events signal progression of the cell cycle
Changes in the cellular cytoskeleton signal progression of the cell cycle
Protein phosphorylation and dephosphorylation events signal the progression of the cell
cycle
In which phase of the cell cycle do sister chromatids exist?
GO
G3
G2
G1
