Imagine that NASA scientists have discovered life on Titan, a moon of Saturn. The first Titanear' organism characterized by NASA also uses standard DNA (i.e. has A, T, G and C bases) to encode its proteins. However, this organism's proteins are found to contain a whopping 350 different amino acids. Assuming the organism uses a "codon" system (i.e. sequences of multiple bases are read as one unit and each codon corresponds to one amino acid), what is the minimum number of bases that must be in each codon to code for this organism's proteins? (Helpful hint: this question is slightly modified from the similar one you've seen before..) 3 4 5 6
