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.

DNA is made up of nucleotides, and proteins are made up of amino acids. The information in DNA is first transcribed into messenger RNA (mRNA) , which is also made up of nucleotides. The process of converting the genetic message found in mRNA to an amino acid sequence (protein synthesis) is called translation.longation continues in this fashion until the stop codon is reached and the peptide chain is released from the ribosome. Translation of proteins involves a mRNA, tRNA, ribosome, and energy. Click on the graphic to learn about translation with the Protein Synthesis animation.
