the flow of genetic information from dna to rna to protein
Watson and Crick proposed that RNA must copy the DNA message in the nucleus and carry it out to the cytoplasm, where proteins are synthesized. Crick also predicted the existence of an adaptor molecule that reads the genetic code and selects the appropriate amino acids to add to a growing polypeptide chain.This proposed flow of genetic information from DNA to RNA to protein became known as the Central Dogma..As it turned out, several types of RNA are involved in the utilization of genetic information. In the nucleus, the DNA code is transcribed, or copied, into a messenger RNA (mRNA) molecule.atson and Crick proposed that RNA must copy the DNA message in the nucleus and carry it out to the cytoplasm, where proteins are synthesized.
