You are excited because your lab is studying the first microorganisms retrieved from Mars! Interestingly, their genetic material consists of a single-stranded nucleic acid with six different nitrogenous bases. Like organisms from Earth, segments of the nucleic acid contain the code for making proteins. If the genetic code in these organisms was read in groups of 2 bases instead of 3, what is the maximum number of amino acids that could be coded for assuming that only one codon functioned as a stop codon? (Enter your answer as a numeral not a word, e.g. enter 17 not seventeen.)
