The Central Dogma
Captions available
The idea
The central dogma states that genetic information flows from DNA to RNA by transcription, then from RNA to protein by translation.
In practice
A gene's DNA sequence is transcribed into mRNA, which is then translated into a chain of amino acids.
Where people slip
The central dogma names the ordinary direction of information flow — it does not claim every process runs in this order without exception.
