Originally landed on: Degeneracy of the Genetic Code
A tRNA molecule is a small strip of RNA folded into a series of loops. One end is attached to an amino acid, and the other end pairs up with the codons on an mRNA.
A codon is a set of three nucleotides, which can be any combination of adenine, uracil, guanine, or cytosine. Adenine matches up with uracil, and guanine matches up with cytosine.
The end of tRNA that pairs with the mRNA codon is called the anti-codon end, because its nucleotides are the matching opposites of the ones in the codon.
