Use this codon chart below to determine the bases that will code for the amino acid Tryptophan (Trp)..
Uracil Cytosine Adenine Guanine
First base
Second Base
Third Base
To determine the bases that will code for the amino acid Tryptophan (Trp) using the codon chart, you would need to look at the Third Base column.
Here is the codon chart:
Uracil Cytosine Adenine Guanine
First base U C A G
Second Base U C A G
Third Base U C A G
From the chart, you can see that Tryptophan (Trp) is coded by the codons UGG.
