The Central Dogma of Biology states that:
DNA codes for RNA through transcription; RNA is translated into an amino acid chain; amino acid chains fold into proteins.
DNA codes for RNA through translation; RNA is transcribed into a protein; proteins fold into amino acid chains.
RNA codes for DNA through translation; DNA is transcribed into an amino acid chain; amino acid chains fold into proteins.
