Study Notes
Mitosis and the Cell Cycle
- The cell cycle is a series of steps a cell undergoes to divide
- Mitosis is a stage in the cell cycle when the cell divides
- Stage 1 (Interphase):
- The cell grows
- Organelles increase in number
- Proteins are synthesized
- DNA replicates (forming an 'X' shape)
- Energy stores increase
- Stage 2 (Mitosis):
- Chromosomes line up at the cell's equator
- Cell fibers pull each chromosome to opposite sides of the cell
- Stage 3 (Cytokinesis):
- Cytoplasm and cell membranes divide
- Two identical daughter cells form
- Importance in multicellular organisms:
- Crucial for growth and development
- Important for replacing damaged cells
- Importance in asexual reproduction:
- Involves one organism
- The organism replicates its cells to produce offspring
- Genetic material:
- The nucleus contains genetic information
