During planetary exploration a new life form is discovered which has a DNA genome containing 6 different bases rather than the familiar four. The life form contains proteins with 25 different amino acids. Codons on Earth comprise three nucleotides; assuming a non-overlapping genetic code that includes initiation and termination codons, how many nucleotides would you predict to constitute a codon in the new life form, assuming all codons to be the same length? Briefly explain your answer.
