I see this phrase come up. What is it referring to?

The three bases that code for an mRNA codon. The ATG that begins the transcription of the mRNA is the decisive triplet that keeps the 'reading frame' in place.
This reading frame is critical, and this is why a single-base deletion (or two-base) is usually deadly for an organism.

Because the genetic code is read as groups of three bases, it is critical that you start at the right place. In the sequence
ACGGTACAG, if you start at the beginning, then you read ACG GTA CAG. If you start with the second or third base, then the message begins CGG TAC and GGT ACA respectively. All three possible starting points are termed 'reading frames', but only one will give the correct message

Three letter amino acid code or start/stop codon.
