Quiz zum Vortrag
Which of the following is TRUE regarding cyclins and cyclin-dependent kinases?
- Cyclins activate cyclin-dependent kinases.
- Cyclins inhibit cyclin-dependent kinases.
- Cyclin-dependent kinases activate cyclins.
- Cyclin-dependent kinases inhibit cyclins.
- There is only one form of cyclin for the cell cycle.
Which of the following is NOT matched correctly?
- G1S checkpoint — reversible checkpoint
- G2M checkpoint — activation of proteins that lead to the production of mitosis machinery
- Spindle checkpoint — irreversible checkpoint
- Spindle checkpoint — production of the anaphase-promoting complex (APC)
- G1S checkpoint — DNA synthesis
Which of the following statements is NOT correct regarding cell-cycle controls?
- There is only one set of cyclin-dependent kinases and cyclins for all checkpoints in the cell cycle.
- Spindle and G1S checkpoints are irreversible clearance points in the cell cycle.
- Clearance of the G2M checkpoint leads to activation of the proteins necessary for the formation of mitosis machinery.
- APC is responsible for the removal of connecting proteins between two sister chromatids.
- During the G1S checkpoint, the binding of cyclin E to Cdk2 triggers the synthesis of various proteins involved in DNA synthesis.
Which enzyme complex is correctly paired with the cell-cycle checkpoint?
- G1S checkpoint － Cdk2-cyclin E
- Spindle checkpoint － Cdk1-cyclin B
- G1S checkpoint － APC
- G2M checkpoint － Cdk5-cyclin A
- Spindle checkpoint － Cdk4-cyclin E

very precise and god, easy to understand and clever way to teach
This is pretty good introduction! haha how to control the cell cycle
Concise with good use of slides and professional presence and dress.
The lecturer did not appear confident looking into notes too often. Too many hand gestures are a distraction especially when not pointing to the stuff on the slides. The material was not presented in an easy or simple way. Made it more complicated that it actually is. I feel difficulty in continuing to the next lectures without understanding this.
