Answer 6 questions correctly in a row.

A codon is a sequence of three nucleotides in an mRNA molecule that corresponds to a specific amino acid. A codon chart shows which amino acid is specified by each codon.

For example, you can use the chart to find the amino acid specified by the codon

AUA.

The first two letters indicate the row and column in which the codon will be found. First, use the leftmost column to identify the row that corresponds with the first letter, A. From there, use the top row to find the column that corresponds with the second letter, U. Then, use the rightmost column to find the last letter, A. The chart shows that the codon AUA specifies the amino acid isoleucine, abbreviated

Ile.
