The transcript of AAT is UUA, which is the code for leucine. Using the chart, first find the U on the left, for the first position. Then, go to the first column to find the U for the second position. This means it has to be either phenylalanine(phe) or leucine(leu(). To determine, use the last letter, A, on the right hand side of the chart. Since this is found in the bottom half of the U-U box, it must correspond to leucine.
<span>The corresponding codon to AAT would be AAU, which would code for Asparagine. During mRNA coding, the tyrosine nucleotides transfer over to uracil, which gives the U in place of the T. Transfer RNA will then code for UUA, the complements to AAT.</span>
the "essential" refers to it being necessary to derive them from the foods we eat, but in fact the amino acids that the body produces are just as essential to the proper functioning and health of our bodies.
