A similar question was posted recently, please note that it is different in nature.

Assume that you work in a laboratory and you are helping to elucidate the genetic code. You have demonstrated experimentally that the triplets UUU and GGG code for phenylalanine and glycine, respectively. A coworker prepares a synthetic, random RNA copolymer using U and G, that in turn is supplied to a cell-free in vitro polypeptide-synthesizing system. An analysis is performed on the polypeptide molecules resulting from the translation of this RNA. Weeks later you are reviewing the procedure and outcome of this experiment in your colleague's data book, and you notice that no record was made of the relative amounts of U and G incorporated into the synthetic RNA. in fact, the only information recorded is that phenylalanine made up 29.6% of the amino acids incorporated into the polypeptide

What were the relative concentrations in which U and G were supplied to the RNA synthesizing system?

I can't figure out how to set up this formula if there is one. I'm grateful for any help.

Explanation / Answer

Phenyl alanine can be coded for UUU or UUC. Considering amino acids utilized only UUU and GGG we could say The concentration of U can be 30% and G can be 70% which resulted in 29.6% of phenyl alanine.
