FAQs on Audio Notes: Cell Cycle and Cell Division Video Lecture - Biology Class 11 - NEET

1. What are the main phases of the cell cycle?

Ans. The cell cycle consists of several key phases: Interphase, which is divided into G₁ (Gap 1), S (Synthesis), and G₂ (Gap 2) phases, followed by the M phase (Mitosis). Interphase is the period of cell growth and DNA replication, while the M phase is when the cell divides to produce two daughter cells.

2. How does mitosis differ from meiosis in cell division?

Ans. Mitosis and meiosis are both processes of cell division but serve different purposes. Mitosis results in two genetically identical daughter cells and is involved in growth and repair, while meiosis produces four genetically diverse gametes (sperm and eggs) through two rounds of division, essential for sexual reproduction.

3. What role do checkpoints play in the cell cycle?

Ans. Checkpoints in the cell cycle are critical control mechanisms that ensure the cell is ready to proceed to the next phase. They monitor factors such as DNA integrity, cell size, and nutrient availability. Key checkpoints are found at G₁, G₂, and during metaphase of mitosis, preventing the division of damaged or unprepared cells.

4. Why is the regulation of the cell cycle important for preventing cancer?

Ans. Regulation of the cell cycle is crucial as it prevents uncontrolled cell growth, which can lead to cancer. Mutations in genes that control the cell cycle, such as proto-oncogenes and tumor suppressor genes, can disrupt normal regulation, allowing cells to divide uncontrollably and form tumors.

5. What are the differences between benign and malignant tumors in relation to cell division?

Ans. Benign tumors are non-cancerous growths that do not invade nearby tissues or spread to other parts of the body, usually resulting from regulated cell division. In contrast, malignant tumors are cancerous, characterized by uncontrolled cell division, invasion of surrounding tissues, and the potential to metastasize to distant sites in the body.
