What is central dogma of molecular biology?
Advertisements
उत्तर
- The central dogma of molecular biology explains the flow of genetic information, from DNA to RNA to make a functional product, a protein
- Genetic information is transferred from DNA to mRNA through transcription and from mRNA to proteins through translation.
- The central dogma of molecular biology was postulated by F.H.C. Crick in 1958.
\[\ce{DNA->[Transcription]mRNA->[Transcription]Polypeptide}\] - It implies that RNA acts as a messenger to deliver the information from DNA to the ribosomes, where it is combined to generate all of our proteins.
