| The 25-bp insertion causes a frameshift mutation and creates stop codons in all three reading frames. |
| Only full-length genomic and cDNA clones, including genes with in-frame stop codons, were analyzed. |
| An organism is defined through the set of preferred codons shaping its genome. |
| The alignment exhibited an insertion of 11 consecutive codons after the first 2 codons in the reading frame of the S gene. |
| In effect, the DNA blueprint is a succession of code words, each consisting of a set of three nucleotides, known as codons, in the gene. |
| The only exception to this rule is that transitions to stop codons are disallowed. |
