Cell Cycle Controls
About the Lecture
The lecture Cell Cycle Controls by Georgina Cornwall, PhD is from the course Cell Cycle and Cell Division.
Included Quiz Questions
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

The lecturer doesn't look confident about the subject. The class seems like is incomplete because the lecturer is unable to explain the content.
Explanations need to be simplified for easier retention. Informative, but not structured for exam retention.
very precise and god, easy to understand and clever way to teach
This is pretty good introduction! haha how to control the cell cycle
