The Central Dogma of molecular biology, first stated by Francis Crick in 1958, describes the flow of genetic information in living beings. Each step leads to the conversion of information which the cell can read and process to carry out its function.

The schematic below can help you get an overall understanding of the Central Dogma. The schematic likens each step to processes in real life to facilitate understanding.
