FAQs on Audio Notes Cell Cycle and Cell Division Video Lecture - Biology Class 11 - NEET
| 1. What are the main stages of the cell cycle? |  |
Ans. The cell cycle consists of several key stages: Interphase, which is further 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 involves the actual division of the cell into two daughter cells.
| 2. What occurs during the M phase of the cell cycle? | |
Ans. During the M phase, the cell undergoes mitosis, which is divided into several sub-stages: prophase, metaphase, anaphase, and telophase. This process ensures that the genetic material is accurately distributed between the two daughter cells. Following mitosis, cytokinesis occurs, which is the division of the cytoplasm, resulting in two separate cells.
| 3. What role do checkpoints play in the cell cycle? | |
Ans. Checkpoints are critical regulatory mechanisms that monitor the progression of the cell cycle. They ensure that the cell is ready to proceed to the next stage by checking for DNA damage, proper DNA replication, and adequate cell size. If any abnormalities are detected, the cell cycle may be halted to allow for repair or, in some cases, trigger programmed cell death (apoptosis).
| 4. How does the cell cycle differ in prokaryotic and eukaryotic cells? | |
Ans. In prokaryotic cells, the cell cycle is simpler and generally consists of a single circular DNA molecule that replicates and divides through binary fission. In contrast, eukaryotic cells have a more complex cell cycle with multiple linear chromosomes, a defined nucleus, and distinct phases of mitosis and cytokinesis. Eukaryotic cells also have multiple checkpoints to regulate the cycle more stringently.
| 5. What is the significance of the G₁ phase in the cell cycle? | |
Ans. The G₁ phase is crucial for cell growth and preparation for DNA synthesis. During this phase, the cell increases in size, synthesises proteins, and produces organelles. It is also a key checkpoint where the cell assesses its environment and internal conditions to determine if it is ready to replicate its DNA in the subsequent S phase.
