Evidence that uracil was substituted for adenine in an RNA molecule.
The DNA coding for a protein regulates the production of that protein through messengers (mRNA) and translators (tRNA). In the nucleus, DNA is changed into RNA. The mRNA transports the information from the nucleus to the cytoplasmic ribosome, where the tRNA translates it into a protein. The primary method by which RNA produces proteins is translation. Genetic information is carried by RNA, which ribosomes transcribe into a range of proteins needed for cellular processes. mRNA, rRNA, and tRNA are the three main RNA subtypes involved in the production of proteins. Protein synthesis, or the process by which amino acids are linked to form proteins, is the most important role of RNA. The ribosomes get information from the nucleus.
