Study Notes
Cell Cycle and Cell Division
- All organisms, including the largest, start their life from a single cell, which grows and divides to form a population of cells.
- Growth and reproduction are characteristics of cells, and all living organisms exhibit these features.
Cell Cycle
- Cell division is a crucial process in all living organisms, involving DNA replication, cell growth, and cell division.
- All these processes must occur in a coordinated way to ensure correct division and formation of progeny cells containing intact genomes.
- The cell cycle refers to the sequence of events by which a cell duplicates its genome, synthesizes other cell constituents, and eventually divides into two daughter cells.
- Cell growth, in terms of cytoplasmic increase, is a continuous process, but DNA synthesis occurs only during one specific stage in the cell cycle.
- Replicated chromosomes (DNA) are distributed to daughter nuclei during cell division through a complex series of events, which are themselves under genetic control.
