    About the Lecture

    The lecture Cell Cycle Controls by Georgina Cornwall, PhD is from the course Cell Cycle and Cell Division.

    Included Quiz Questions

    1. G1 to S to G2 to mitosis to cytokinesis
    2. G1 to G2 to S to mitosis to cytokinesis
    3. G1 to S to G2 to cytokinesis to mitosis
    4. S to G1 to G2 to mitosis to cytokinesis
    1. G2
    2. G1
    3. S
    4. M
    1. APC — phosphorylation of DNA polymerase
    2. G2M checkpoint — commitment to mitosis
    3. Spindle checkpoint — deal with DNA separation
    4. G1S — deals with DNA synthesis
    5. MPF — assess the success of DNA synthesis
    1. There is only one set of Cdk and cyclins to control the cell cycle checkpoints to make the process a less complicated cell chore
    2. Spindle and G1S checkpoints are irreversible clearance points in the cell cycle
    3. Clearance of G2M phase leads to the activation of proteins necessary for the formation of mitosis machinery
    4. Anaphase promoting complex (APC) involves removal of cohesion from the chromosomes during separation of sister chromatids
    5. During G1S checkpoint, the binding of cyclin E to Cdk2 triggers the synthesis of various proteins involved in DNA synthesis
