One оf the strаtegies used by reseаrchers tо determine which аminо acids were coded by which codon sequences was to add polynucleotide phosphorylase, an enzyme that randomly polymerizes ribonucleotides together, to a tube with different ratios of nucleotides. The RNAs were then translated in vitro and the proportion of different amino acids in the translated proteins were then determined. If uracil and adenine were added to a tube in a ratio of 1 uracil: 4 adenine (20% uracil and 80% adenine), what proportion of the amino acids in the proteins made would be tyrosine (you will need to use the codon table unless you have it committed to memory)? Please carry out your answer to 3 decimal places.   Using the codon table what proportion of the amino acids in the proteins made would be isoleucine? Please carry out your answer to 3 decimal places.
