This works not because choice() takes a string, but because
even though it takes a sequence, a string *is* a sequence

Just use another sequence, either a tuple or a list:
random.choice(("rna", "rnb", "rnc"))
random.choice(["rna", "rnb", "rnc"])
The latter is preferred for various mostly stylistic reasons...
