A rare disease is now understood to be caused by a single mutant gene. When the researcher learns that the gene encodes a ________, he says “Oh good! We may be able to treat the disease with recombinant protein produced in E. coli and delivered by injection.”

If mRNA is complementary to the DNA template strand and the DNA template stand is complementary to the DNA non-template strand, why are base sequences of mRNA and the DNA non-template strand not identical? Could they ever be?
