MITOSIS AND MEIOSIS
- Meiosis and mitosis are cell division processes vital for the growth, development, and
maintenance of organisms.
Mitosis and meiosis are two distinct processes of cell division, each serving a specific purpose in
organisms. While mitosis is responsible for growth and tissue repair, meiosis plays a crucial role
in sexual reproduction and generating genetic diversity among offspring. Understanding these
processes is fundamental in biology and genetics.
Mitosis
Mitosis is a type of cell division that results in two daughter cells, each having the same number
of chromosomes as the parent cell. It is responsible for growth, tissue repair, and asexual
reproduction.
Stages of Mitosis:
1. Interphase: The cell prepares for division by duplicating its DNA (chromosomes) during the
S phase of interphase.
2. Prophase: Chromosomes condense and become visible. The nuclear envelope begins to
break down.
3. Metaphase: Chromosomes align at the cell's equatorial plane (metaphase plate).
4. Anaphase: Sister chromatids are pulled apart and move to opposite poles of the cell.
5. Telophase: New nuclear envelopes form around the separated chromatids, resulting in two
distinct nuclei.
6. Cytokinesis: The cell's cytoplasm divides, creating two identical daughter cells.
Mitosis is responsible for the growth and repair of somatic (body) cells. It ensures that each
daughter cell has the same genetic information as the parent cell.
Mitosis produces two diploid (2n) daughter cells, each with the same chromosome number as the
parent cell.
