FAQs on Cell Cycle & Division in One Shot (NCERT) Video Lecture - Biology Class 11 - NEET
| 1. What is the cell cycle and division? |  |
Ans. The cell cycle is the series of events that take place in a cell leading to its division and duplication. It consists of interphase, where the cell grows and DNA replicates, and mitosis or meiosis, where the cell divides into two or four daughter cells respectively.
| 2. What are the different phases of the cell cycle? | |
Ans. The cell cycle consists of four main phases: G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis). During G1, the cell grows and carries out its normal functions. In S phase, DNA replication occurs. G2 phase is a preparation phase before cell division. Finally, during M phase, the cell divides into two daughter cells through mitosis or meiosis.
| 3. How is the cell cycle regulated? | |
Ans. The cell cycle is regulated by a complex network of proteins and checkpoints. Cyclin-dependent kinases (CDKs) and cyclins play a crucial role in regulating the cell cycle. CDKs control the progression from one phase to another, while cyclins activate CDKs at specific stages. Checkpoints monitor the integrity of DNA and ensure proper cell division.
| 4. What happens during mitosis? | |
Ans. Mitosis is the process of cell division where a parent cell divides into two genetically identical daughter cells. It consists of four stages: prophase, metaphase, anaphase, and telophase. During prophase, chromosomes condense, and the nuclear envelope breaks down. In metaphase, chromosomes align in the middle of the cell. Anaphase involves the separation of sister chromatids, and in telophase, two new nuclei form around the separated chromosomes.
| 5. What is the significance of cell cycle and division? | |
Ans. Cell cycle and division are essential for growth, development, and maintenance of organisms. They are crucial for tissue repair, wound healing, and the production of new cells. Proper regulation of the cell cycle ensures that genetic material is accurately replicated and distributed to daughter cells, preventing abnormalities and maintaining the overall health of an organism.
