central dogma The relationship among the steps from DNA to the production of a protein. The synthesis of messenger RNA from DNA, and the movement mRNA out of the nucleus (transcription). Carries the genetic code into the cytoplasm.

Central dogma: A phrase that refers to the concept of information flow proceeding only from DNA to RNA to protein.

Central dogma of molecular biology
: DNA is transcribed into RNA and RNA is translated into protein only in this direction. This concept is first proposed by Francis Crick in 1957. For more, see

"Central Dogma"
Watson and Crick's model attracted great interest immediately upon its presentation. Arriving at their conclusion on February 21, 1953, Watson and Crick made their first announcement on February 28.

Crick's central dogma. Information flow (with the exception of reverse transcription) is from DNA to RNA via the process of transcription, and thence to protein via translation. Transcription is the making of an RNA molecule off a DNA template.

Expanded Central Dogma of Molecular Biology
In the flow of information from genotype to phenotype, two steps require the copying of nucleotide sequence information into a different form.

Has the "central dogma" changed?
Well, it used to be thought that a gene would encode a single protein, and now we know that a gene might encode ten or even more different variants of that protein.

Central dogma. Francis Crick's seminal concept that in nature genetic information generally flows from DNA to RNA to protein. Centrifugation. Separating molecules by size or density using centrifugal forces generated by a spinning rotor.
