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.

The DNA contains the master plan for the creation of the proteins and other molecules and systems of the cell, but the carrying out of the plan involves transfer of the relevant information to RNA in a process called transcription. The RNA to which the information is transcribed is messenger RNA (mRNA).The process associated with RNA polymerase is to unwind the DNA and build a strand of mRNA by placing on the growing mRNA molecule the base complementary to that on the template strand of the DNA.he RNA to which the information is transcribed is messenger RNA (mRNA).
