(149).jpg "The Cell Cycle - Quiz")
Let's review a little about the cell cycle and its components to understand colectoral cancer.
- 1.
How many phases to the cell cycle are there?
- A.
1
- B.
3
- C.
4
- D.
5
Correct Answer
C. 4 -
- 2.
What phases make up the cell cycle?
- A.
Gap 1, Synthesis, Meiosis, Calvin Phase
- B.
Gap 1, Synthesis, Gap 2, Mitotic Phase
- C.
Gap 1, Gap 2, Mitotic Phase, Cell Signaling Pathway
- D.
Mitotic Phase, Synthesis, Growth 1, Growth 2
Correct Answer
B. Gap 1, Synthesis, Gap 2, Mitotic Phase -
- 3.
What occurs during the Mitotic phase of the cell cycle?
- A.
Replication of DNA
- B.
Cell growth of organelles and proteins
- C.
Division of cells into haploid gametes
- D.
Mitosis and Cytokinesis
Correct Answer
D. Mitosis and Cytokinesis -
- 4.
What is the role of cyclins and CDKs in the cell cycle?
- A.
Cyclins activate cyclin-dependent kinases that form the protein kinase during G2
- B.
Cyclins are a regulatory protein while CDKs are protein kinases that are active only when attached to particular cyclin that regulate transition out of fap phases
- C.
Cyclins are named for the "roundness" of the cell cycle and CDKs are the proteins that prmote this "roundness"
- D.
Cyclins and CDKs do not have a role in the cell cycle
Correct Answer
B. Cyclins are a regulatory protein while CDKs are protein kinases that are active only when attached to particular cyclin that regulate transition out of fap phases -
- 5.
MPFs stand for what and do what?
- A.
Mitotic Proten Function that aids in development and functioning of proteins
- B.
Maturation Promoting Factor that promotes DNA maturation
- C.
Maturation Promoting Factor that includes cyclins and CDks and triggers progression through the cell cycle
- D.
Maturation Promoting Factor that does not serves to speed up cancer
Correct Answer
C. Maturation Promoting Factor that includes cyclins and CDks and triggers progression through the cell cycle -
- 6.
