Cell Cycle M Phase
1. What is Mitosis?
Mitosis is a cellular division where a single cell divides into two identical daughter cells, each with the same number of chromosomes as the parent cell. It plays an important role in growth, development, and tissue repair in multicellular organisms.
2. What is the Longest Phase of Mitosis?
The longest phase of mitosis is prophase, during which chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form, preparing for the subsequent stages of cell division. It marks the initiation of the orderly separation of genetic material.
3. What is the Importance of Cell Division?
Cell division is important for cell growth, tissue repair, and reproduction in organisms. It ensures the maintenance of cell numbers and genetic stability across generations and plays an important role in development and the renewal of damaged or aging cells.
4. What is the Shortest Period of Mitosis?
The shortest period of mitosis is anaphase, characterized by the rapid separation and movement of sister chromatids towards opposite poles of the cell, ensuring equal distribution of genetic material to daughter cells.
5. What are the Four Major Stages of Mitosis?
The four major stages of mitosis are prophase, metaphase, anaphase, and telophase. These stages collectively ensure the accurate distribution of genetic material during cell division.
Mitosis – Overview, Phases, & Significance Class Notes
Cell Cycle M phase, or mitotic phase, is an important stage in the cell cycle responsible for cell division. Mitosis is a process where a single cell divides into two identical daughter cells. The process of mitosis consists of two main steps: karyokinesis, which involves the division of the cell nucleus, and cytokinesis, which is the separation of the cytoplasm and other organelles. The four stages of mitosis are prophase, metaphase, anaphase, and telophase. Cytokinesis completes the cell cycle and is responsible for the physical division of a parent cell into two daughter cells. It helps in the survival and growth of organisms, maintenance of chromosome number, and repair of damaged cells.
