Biology textbooks explain that cells follow a universal rule when processing gene transcripts to make proteins. Non-coding snippets of RNA are bracketed by a guanine-thymine (GT) nucleotide sequence on one end and an adenine-guanine (AG) sequence on the other—unmistakable signposts telling the cell exactly what sequences to leave out and what should stay in.
