Etymologically, the entry records: From ribosomal + ribonucleic acid, from being the ribonucleic acid found in ribosomes. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is ribosomal ribonucleic acid, spelled R-I-B-O-S-O-M-A-L- -R-I-B-O-N-U-C-L-E-I-C- -A-C-I-D, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
