1.) How do cyclins and CDKs interact in controlling the cell cycle?
| Cyclins, whose levels fluctuate during the cell cycle, inactivate CDKs by binding to them. |
| CDKs, whose levels fluctuate during the cell cycle, degrade the enzymatic activities of cyclins by binding to them. |
| CDKs and cyclins both fluctuate in levels during the cell cycle but fail to bind to each other. |
| Cyclins, whose levels fluctuate during the cell cycle, activate CDKs by binding to them. |
| CDKs, whose levels fluctuate during the cell cycle, enhance the enzymatic activities of cyclins by binding to them. |
2.)
What causes genomic instability?
| A mutation in a cell-cycle checkpoint gene that results in multiple chromosomal rearrangements and aneuploidy |
| A malfunction in the mitotic spindle checkpoint |
| A mutation in a DNA repair gene that results in a defect in the repair of chromosomal breaks |
| All of the above cause genomic instability. |
| None of the above causes genomic instability. |
3.)
Tumor cells are considered to be malignant if:
| they divide and form a mass. |
| they invade other tissues. |
| they establish in new locations. |
| A and B. |
| All of the above. |
