Question 3

Examples of Stimulating and inhibitory proteins.

Answer 3

Stimulating
proto-oncogene, cyclins, growth factors
Move the cell into the next stage of the cell cycle
Inhibitory
prevent activation of CDK-cyclins
MAD
p53

Question 4

What is the order of events for cell cycle regulation.

Answer 4

1. Growth factors are released
2. Cyclin levels increase
3. Cyclin complexes form activate CDk
4. CDK activates the next phase.
