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.
Learn about the amazing process of cell growth and reproduction, where single cells divide into two daughter cells, giving rise to new life. Understand the basics of cell division and its importance in living organisms.
