Reverse complement leaves ambiguity symbols untranslated · case 05

Reverse complement leaves ambiguity symbols untranslated.

Member previewVariant 5 · 3 implementations · 6 checks per implementation

Case contract

Reverse the string then substitute A:T,T:A,C:G,G:C,R:Y,Y:R,N:N,-:-. Inputs use only this explicit uppercase alphabet.

Why this case matters

An offline abstract sequence-data model; useful for testing representation invariants without biological inference.
