Example, AUG using the Genetic Code Table. Look for the first letter of the MRNA
codon on the left side of the genetic code table (A). The second letter of the MRNA
on the second letter column (U) and the third letter on the right-side column (G).

Using your sample DNA, unzipped and second strand removed, you will first create an RNA strand (transcription). DNA is read in the 5' → 3' direction, so when you create RNA, a 3'end pairs with the 5' end of DNA. From your RNA strand, you will need to create codons; remember that a codon is a group of 3 bases that codes for a specific amino acid. Your codons are read in the 5' → 3' direction (hint: it might be right to left!). You will then need to convert your codons into amino acids in the 5' → 3' direction (translation).
