b. The cell controls the concentration of nucleotides available for DNA synthesis.

c. The cell allows DNA to be replicated only if it lacks damage.

d.The cell controls synthesis of machinery required to make more proteins.

e. The cell synthesizes CKI's that block cyclin/CDK activity after initiation of DNA replication.

6. What happens if a cell is unable to destroy M-cyclin at the end of a cell cycle ?

a. The cell will be unable to enter mitosis.

b. The cell will be unable to complete mitosis.

c.The cell will complete mitosis early.

d.The cell will fail to disassemble its nuclear membrane.
