Eurkaryotic Cell Cycle

Question 1

The enzymes and proteins necessary for cell division are

synthesized in which phase

Answer 1

G2

Question 2

A mutation in Cyclin E that interferes with its binding
to Cdk2 would prevent which of the following
processes?

Answer 2

Passage from G1 to S

Question 3

The DNA checkpoint kinases, Chk1 and Chk2, phosphorylate Cdc25
resulting in its inhibition. Cdc25 is required for the activation of
both Cdk1 and Cdk2. Inhibition of Cdk1 would lead to?

Answer 3

G2 phase arrest

Question 4

What effect would a mutant of Rb that can no longer be phosphorylated by
Cdk4/Cdk6 have on progression through the cell cycle?

Answer 4

Transcription of genes necessary for cell cycle progression would be
repressed

Question 5

Growth factors induce the synthesis of

Answer 5

Cyclin D
