Life forms on a newly discovered exo-planet (planet found outside of our solar system) are very similar to those found on earth, except their proteins are made of 128 different amino acids. otherwise, their dna and rna compositions are identical to those found on earth. this observation suggests that the codons coding for the amino acids are likely to be at least how many bases long?
