DNA -- RNA -- TRNA--- amino acid--- protein
DNA (DeoxyRiboNucleicacid) creates RNA (RiboNucleicAcid) which is DNA basically cut in half vertical this then is "translated into a code of amino acids" by TransferRNA then these codons (3 bases grabbed by transferRNA) are turned to amino acids from there after the sequence is done you have a protien full of information on what to do
C. their DNA is very different
