Reverse complement leaves ambiguity symbols untranslated · case 02
Reverse complement leaves ambiguity symbols untranslated.
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.
One recorded failure
