- Which of the following would result in cell cycle arrest? O phosphorylation of Rb by G1-Cdk phosphorylation of p53 O phosphorylation of helicase by S-Cdk phosphorylation of M-Cdk by CAK phosphorylation of APC by M-CdkThe destruction of the various cyclins is commonly used to inactivate the Cdk/cyclin complexes. Why is it advantageous to inactivate these complexes via protein destruction instead of some other method that does not require the re-synthesis of a cyclin protein the next time the cell divides?Which of the following is false about cyclin-cdk complexes? OCdk's do not have to bind to cyclin proteins for complex to be active. OCdk/cyclin complexes phosphorylates proteins required to trigger next cell cycle phase. Process acts as molecular brakes to ensure cell is ready to continue with cell cycle. O Cyclin concentrations increase gradually, but cdk must be phosphorylated by specific kinase for complex to be active
- // Which one of these does CDK1/cyclin mitotic kinase NOT do to induce mitosis? Phosphorylates Histone H1 to condense chromosomes Phosphorylates pore proteins to disassemble pores Phosphorylates transcription factors to shut off transcription Phosphorylates lamins for lamin assemblyThe cell cycle contains a series of events that control the division of cells. It is controlled by which of the following: P. dephosphorylation of cyclin-dependent kinases (S) Q. binding of CDK inhibitor proteins (R) R. cyclin synthesis and degradation (P) S. phosphorylation of cyclin-dependent kinases (Q) R and S P, Q, R, and S Q and R P and QYou are studying three proteins that you think are important Yor progression through the cell cycle. You know that one of them is a phosphatase (P1) and the other two are kinases ( K1 and K2). You add these enzymes in different combinations as shown below, and find that they have different effects on the activity of a cyclin dependent kinase, cdk2p. cdk2p Inactive Active cdk2p + K1 cdk2p + K2 Inactive cdk2p + K1 + K2 Inactive cdk2p + P1 cdk2p + P1 + K2 cdk2p + P1 + K1 Inactive Inactive Active cdk2p + P1 + K1 + K2 Active
- 13) A phosphotase removes an inhibitory phosphotyrosine phosphate from the serine protein kinase, in MPF whcih activates the kinase and triggers the initiation of mitosis. true or falseAfter DNA damage (e.g. caused by X-ray exposure) in eukaryotic cells, the cell cycle can be arrested by the stabilisation of the protein which drives the transcription of the gene, whose protein product interacts with the G1/S-Cdk and S-Cdk complexes. O PDGF, acetyltransferase O phenylalanine hydraxylase, PDGF O p53, acetyltransferase O p53, p21 O p21. p53The following figure shows how the activities (y-axis) of Cdk-Cyclin B complex and the APC complex change through the cell cycle.

- Which change is most likely to directly interfere with cytokinesis in a dividing animal cell? The loss of a lysine residue in a histone protein A mutation that affects the G2-M cyclin-CDK complex A mutation in the gene that encodes actin A mutation that affects the S cyclin-CDK complex A mutation in the RB geneWhat would be the effect on the cell cycle if a cell acquired a mutation that rendered each of the following domains inactive? Explain your reasoning. The PSTAIR region of an M-phase Cdk The Wee1 Kinase The kinase that normally phosphorylates Sic 1 The Sic1 cyclin-Cdk inhibitorDiagram (just use arrows in the same way you diagrammed in a former test a stimulus leading to the activation of PKC, for example) in as much detail as possible what happens to a mammalian cell when it is irradiated, leading to when the cycle stops due to DNA damage. Include and name the famous mammalian checkpoint protein known by its molecular weight, as well as name another protein it activates. This other protein's function can be described by a 3 letter acronym that contains the letter K. Mention the acronym. 1.
