A hybrid protein that’s part human and part bacterial. The production of a human protein in a bacterium can occur because: A. Humans and bacteria use exactly the same codons to specify each amino acid. B. Humans and bacteria both use almost the same codons to specify amino acids. C. Humans and bacteria use different codons, but there is enough similarity that the protein made by bacteria still works. Where does translation begin on the mRNA? A. Where ever there is an AUG in the mRNA B. At a ribozyme within the Ribosome C. At a section of DNA called the promoter D. At a particular AUG in the mRNA
