What would most likely happen if M-cyclin is replaced by a nondegradable M-cyclin? A : The cell cycle would proceed as normal B : The cell cycle would not initiate and the cells would remain in G0. C : Cells would complete one cell cycle but would not start the next cell cycle. D : Cells would complete G1, S, and G2, but cannot enter the M phase. E : Cells would enter M phase but would not exit mitosis.

2. Cyclin B plus CDC2 are necessary for a checkpoint at the G2->M transition that makes sure chromosomes are intact before mitosis begins. If you irradiate cells in G2 phase with gamma rays, which damages the DNA that was successfully replicated in S-phase, cells delay entry into mitosis until the DNA damage is repaired. If you inactivated that Cyclin B/ CDC2 checkpoint with the drug wortmannin and irradiated cells in G2, what would happen? a) Cells would never enter mitosis...

In most cells, where do all microtubules originate? What is the difference between a kinetochore and a centromere? During mitosis, the breakdown of the nuclear envelope depends on the: a. disassembly following proteasomal degradation of intermediate filaments. b. disassembly of lamin filaments following phosphorylation by mitotic cyclin/cdk complexes. c. ubiquitination of mitotic cyclin proteins. d. lamin filament dephosphorylation by cdc14. Which of the following occurs during anaphase A? a. The spindle elongates. b. Kinetochores remain attached to shortening kinetochore microtubules....
