The central dogma of molecular biology deals with the flow of genetic information within a biological system. It is often stated as "DNA makes RNA, and RNA makes protein", [1] although this is not its original meaning. It was first stated by Francis Crick in 1957, [2] [3] then published in 1958: [4] [5] The Central Dogma.
The central dogma plays a key role in the study of molecular genetics. The central dogma states that DNA replicates itself, DNA is transcribed into RNA, and RNA is translated into proteins. [24] Along with the central dogma, the genetic code is used in understanding how RNA is translated into

The US, where genetics had developed the most rapidly, and the UK, where there was a coexistence of both genetics and biochemical research of highly advanced levels, were in the avant-garde. Germany, the cradle of the revolutions in physics, with the best minds and the most advanced laboratories of genetics in the world, should have had a ...
This is commonly known as the central dogma of molecular biology, i.e. information flows from nucleic acid to protein and never from protein to nucleic acid. Following this adaptor insight, Brenner conceived of the concept of messenger RNA during an April 1960 conversation with Crick and François Jacob , and together with Jacob and Matthew ...
Collectively, this body of research established the central dogma of molecular biology, which states that proteins are translated from RNA, which is transcribed from DNA. This dogma has since been shown to have exceptions, such as reverse transcription in retroviruses. The modern study of genetics at the level of DNA is known as molecular genetics.
[28] This is because it was the first comprehensive insight into genetic information (later called the central dogma of molecular biology), protein synthesis (known as the sequence hypothesis), the role of RNA (the adaptor hypothesis) as well as the existence of genetic code. [3]
1941: Edward Lawrie Tatum and George Wells Beadle show that genes code for proteins; [22] see the original central dogma of genetics. 1943: Luria–Delbrück experiment: this experiment showed that genetic mutations conferring resistance to bacteriophage arise in the absence of selection, rather than being a response to selection.
