Representative sequencing pyrograms of codon 1058 in faecal RNA samples. A: Pyrogram with an ATG (codon = methionine) sequence at position 1058 from cat 32, faeces. The peaks represent a sequence of GCTATG GG. B: Pyrogram with a TTG (codon = leucine) sequence at position 1058 from cat 46, faeces. The peaks represent a sequence of GCCTTG GG. C: Pyrogram with a mixture of ATG (codon = methionine) and CTG (codon = leucine) sequences at position 1058 from cat 60, faeces. The peaks represent a sequence of GCT(C/A)TG GG; the relative peak heights suggest that the methionine and leucine encoding RNAs were present in approximately equal amounts. The horizontal axis shows the nucleotide dispensation order. E, enzyme-only control; S, substrate-only control. The initial nucleotide injected (C) is irrelevant to the sequence and provides a baseline.
