FAQs on Cell Cycle & Its Phases Video Lecture - Biology Class 11 - NEET
| 1. What is the cell cycle and why is it important? |  |
Ans. The cell cycle is the series of events that a cell goes through as it grows and divides into two daughter cells. It is important because it ensures the proper growth, development, and maintenance of an organism. It allows cells to replicate their DNA and divide into new cells for tissue repair, growth, and reproduction.
| 2. What are the main phases of the cell cycle? | |
Ans. The main phases of the cell cycle are interphase, mitosis, and cytokinesis. Interphase is the longest phase and is divided into three subphases: G1 (growth phase 1), S (DNA synthesis phase), and G2 (growth phase 2). Mitosis is the phase where the cell's nucleus divides into two identical nuclei, and cytokinesis is the final phase where the cytoplasm divides, resulting in two separate daughter cells.
| 3. How is the cell cycle regulated? | |
Ans. The cell cycle is tightly regulated by a complex network of proteins and checkpoints. Cyclin-dependent kinases (CDKs) and cyclins are key regulators that control the progression of the cell cycle. Checkpoints ensure that the cell cycle proceeds accurately and that any errors or DNA damage are repaired before the cell continues to divide.
| 4. What happens if the cell cycle is not properly regulated? | |
Ans. If the cell cycle is not properly regulated, it can lead to various problems, including uncontrolled cell growth and division, which can result in the formation of tumors and cancer. On the other hand, if the cell cycle is slowed down or halted, it can lead to impaired tissue development and repair, causing issues in growth and overall organismal health.
| 5. How do cancer cells differ from normal cells in terms of the cell cycle? | |
Ans. Cancer cells differ from normal cells in terms of the cell cycle as they have lost the ability to regulate their cell division properly. They often have mutations in genes that control cell cycle checkpoints, leading to uncontrolled cell growth and division. Cancer cells can divide rapidly, form tumors, invade nearby tissues, and spread to other parts of the body through a process called metastasis.
