Cell Biology - Cell Cycle & Division

⏱ Time: 0s

Q1. What is the significance of the G2 phase in the cell cycle? (2022)

Solution:

The G2 phase is crucial for preparing the cell for mitosis, ensuring all DNA is replicated and the cell is ready to divide.

⏱ Time: 0s

Q2. In which phase do sister chromatids separate and move to opposite poles of the cell? (2019)

Solution:

During Anaphase, sister chromatids are pulled apart and move towards opposite poles of the cell.

Q3. In which phase do sister chromatids separate and move towards opposite poles? (2022)

Solution:

During Anaphase, sister chromatids are pulled apart and move towards opposite poles of the cell.

Q4. In which phase do sister chromatids separate and move to opposite poles? (2019)

Solution:

During Anaphase, sister chromatids are pulled apart and move toward opposite poles of the cell.

Q5. What is the role of cyclins in the cell cycle? (2019)

Solution:

Cyclins are proteins that regulate the progression of the cell cycle by activating cyclin-dependent kinases (CDKs).

Q6. What is the term for the division of the cytoplasm during cell division? (2020)

Solution:

Cytokinesis is the process that divides the cytoplasm of a parental cell into two daughter cells.

Q7. Which of the following is NOT a stage of the cell cycle? (2019)

Solution:

Synthesis is not a stage of the cell cycle; it refers to the S phase where DNA is replicated.

Q8. In which phase of the cell cycle does the cell spend the majority of its life? (2021)

Solution:

The G1 phase is where the cell spends most of its life, performing normal functions and growing.

Q9. In which phase of the cell cycle does cytokinesis occur? (2021)

Solution:

Cytokinesis occurs during the M phase, following mitosis, to divide the cytoplasm and form two daughter cells.

Q10. Which phase follows metaphase in mitosis? (2023)

Solution:

Anaphase follows metaphase, where sister chromatids are pulled apart to opposite poles of the cell.
