"The central dogma of molecular biology describes the flow of genetic information. It was first described by Francis Crick in 1956 as one-way traffic: as: "DNA makes RNA and RNA makes protein."
A recent paper published in Mutation Research -- Fundamental and Molecular Mechanisms of Mutagenesis, however suggests that, rather than being a one-way street, DNA-directed RNA transcription may have profound adaptability. The authors of the paper showed a conceptually novel relationship between the genotype (DNA) and the phenotype (the products of the transcription of DNA)."
