Learn about the central dogma of molecular biology, which is the flow of genetic information from DNA to RNA to protein. Understand the steps of transcription and translation, and the genetic code, with examples and quiz.
2 days ago · The central dogma of molecular biology is a theory stating that genetic information flows only in one direction, from DNA, to RNA, to protein, or RNA directly to protein.
Apr 17, 2021 · The central dogma was proposed by Francis Crick in the late 1950s. This trailblazing theory suggested that genetic information flows primarily from nucleic acids in the form of DNA and RNA to functional proteins during the process of gene expression.
A gene that encodes a polypeptide is expressed in two steps. In this process, information flows from DNA → RNA → protein, a directional relationship known as the central dogma of molecular biology.
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", although this is not its original meaning. It was first stated by Francis Crick in 1957, then published in 1958: The Central Dogma.
As you have learned, information flow in an organism takes place from DNA to RNA to protein. DNA dictates the structure of mRNA in a process known as transcription, and RNA dictates the structure of protein in a process known as translation. This is known as the Central Dogma of Life.
