Preferential conservation of uAUGs in mouse–rat stop-codon-bounded 5′-UTR alignments (5′-UTR<stop set)
| Trinucleotide | Triplet present in mouse, but not in rat (%) | Triplet conserved in mouse and rat (%) | Triplet present in rat, but not in mouse (%) |
|---|---|---|---|
| AUG | 11 | 80 | 9 |
| AGU | 15 | 67 | 18 |
| GUA | 18 | 57 | 25 |
| GAU | 16 | 68 | 16 |
| UAG | 17 | 62 | 21 |
| UGA | 14 | 70 | 16 |
Fishers's exact test: 499 conserved uAUGs, 124 non-conserved uAUGs, 3262 conserved AGU/GUA/GAU/UAG/UGAs, 1675 non-conserved AGU/GUA/GAU/UAG/UGAs and P = 3.53 × 10−13.
