Proteins are built on the ribosomes. The mRNA is the string with the instructions, and the tRNA brings the amino acids (the parts that are used to build the proteins.)
Each codon has 3 letters or bases.
DNA has 4 letters or bases: AT CG adenine, thymine, cytosine, guanine.
RNA has 4 letters or bases: AU CG adenine, URACIL, cytosine, guanine.
The letters or bases can be arranged in a practically infinite number of ways.
DNA has the instructions for making proteins.
