For scenarios 1-3 answer the following questions; a) What stage of the cell-cycle would be affected? b) How would the stage in (a) be affected i.e. regarding DNA content or general appearance of the cell? 1. A mutant form of cyclin B is activated too early (at the end of S-phase, instead of acting at G2/M). 2. A mutant form of a G1/S checkpoint protein has no activity. 3. A mutant form of a spindle checkpoint assembly protein has no activity.

Describe the general conditions that must be met at each of the three main cell-cycle checkpoints.
Q. Cyclins and CDK(inase) complexes regulate the cell cycle. Which of the following statements is true? A. Cyclins activate CDKs which remove phosphates from other proteins. B. Cyclins activate CDKs which add phosphates to other proteins. C. CDKs activate cyclins which remove phosphates from other proteins. D. CDKs activate cyclins which add phosphates to other proteins.
What are cell cycle checkpoints? Where in the cell cycle are the checkpoints found (note—incude S phase checkpoint? How do they differ? How are Rb, p53, and MPF involved in cell cycle checkpoints? What events could lead to cell cycle arrest?
In class, we talked about flow cytometry which allows scientists to determine what stage of the cell cycle cells are in by measuring their DNA content. Draw what the graph would look like for the mutant below at a 0-time point when there are 1000 cells total, with 5000 cells in G1, 350 cells in M and G2, and 150 cells in S phase. And then a graph of 1 hour later when the cells should have competed for mitosis: → loss of function of cdc25
Explain why we can say that M-phase of the cell-cycle is triggered by a positive feedback loop. a) What would the consequences be if cohesins were working normally but condensins were not? and b) what stage of the cell cycle would this cause problems in? Why is it important for the centrosome to duplicate during G1-G2 (interphase) before M phase? The kinetochores serve as a link between the sister chromatids and the microtubules attached to the mitotic spindle. a) How are microtubules still able to exhibit dynamic instability after they are bound to the sister chromatids and b) why is this important to mitosis? As the name suggests, the Anaphase-promoting-complex (APC), promotes the 4th phase of mitosis by separating the sister chromatids so they can travel to separate poles of the cell, and prevents them from being re-zipped together. Describe how APC does these two things (Hint: one involves M-cyclin and the other involves…
1.Colchicine is a type of drug that inhibits the microtubule formation during the cell division. Let’s say that the onion root tip (a place where most of the plant’s cells divide) was submerge in colchicine solution. a. How do you think will be the cell’s respond? Will it continue its cell division? Why or why not? b. Let’s say that the cells in onion root tip treated with colchicine were not halted at spindle checkpoint. What do you think will happen during the division?
Leland Hartwell, the third recipient of the 2001 Nobel Prize in Physiology or Medicine, was acknowledged for his characterization of cell cycle checkpoint pathways in the budding yeast S. cerevisiae. What is a cell cycle check-point pathway?
Which of the following need to be expressed to get past the G1 checkpoint and why? Select one: a. All the answers are correct and needed to progress the cell past the G1 checkpoint by expressing the enzymes necessary for DNA replication. Once these proteins are all expressed, the cell has moved past G1 into S phase. b. Primase because this enzyme is needed for DNA replication moving the cell from G1 to S. c. Cyclins because the accumulation of specific cyclins will turn on CDKs needed to turn on gene expression for proteins involved in DNA replication, moving the cell from G1 to S. d. DNA helicase because this protein is needed for DNA replication (part of S phase). So expression will help progress the cell from G1 to S.
What aspects of the cell cycle are controlled by the G1, G2, and M checkpoints? How are cyclins and cyclin-dependent protein kinases involved in cell cycle regulation at checkpoints?

Which of the following statements about the cell cycle is TRUE? a. The protein APC blocks cells from entering anaphase b. CDKs are degraded after each cell cycle phase by the addition of a ubiquitin chain to the proteins c. A kinase is a protein that adds a ubiquitin chain to other proteins Cyclin activity is necessary, but not always sufficient, for CDK activation d. Cyclin proteins must be degraded before Cdk proteins can be activated
