I make it #300#.

Explanation:

A codon codes for each specific amino acids, and is made up of a triplet of nucleotides, i.e. three nucleotides. Therefore, we can say that three nucleotides will code for one amino acid.

Therefore for #900# nucleotides, we would make:

#(900color(red)cancelcolor(black)"nucleotides")/(3color(red)cancelcolor(black)"nucleotides""/amino acid")=300 \ "amino acids"#
