Central Dogma of Molecular Biology
Protein synthesis requires two steps: transcription and translation.
DNA contains codes ...
Central dogma. Francis Crick's seminal concept that in nature genetic information generally flows 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 Gene Expression.

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.
The central dogma of molecular biology states that all of the information that makes you unique is housed in the nucleus of every cell in your body in the form of DNA. The human DNA is a string of 3.2 billion base pairs.
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.
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.

Initially, this hypothesis was highly controversial, because it seemed to contradict the "central dogma of modern biology", which asserts that all living organisms use nucleic acids to reproduce.
And you may have heard about the central dogma, which is DNA, to RNA, to protein. Well, transcription refers to that first part of going from DNA to RNA. And we transcribe DNA to RNA in specific places.
Crick hypothesized the mechanism for DNA replication and further linked DNA to proteins, an idea since referred to as the central dogma.
Students using the module should be familiar with Mendelian genetics, the chromosome theory of inheritance (including genetic linkage and recombination), the chemical nature of the gene (including the structure of DNA), and the central dogma, ...
