Asample ( 885 mg ) of an oligomeric protein of m r 155,000 was treated with an excess of 1‑fluoro‑2,4‑dinitrobenzene (sanger's reagent) under slightly alkaline conditions until the chemical reaction was complete. the peptide bonds of the protein were then completely hydrolyzed by heating it with concentrated hcl . the hydrolysate was found to contain 4.85 mg of dnp‑val. 2,4‑dinitrophenyl derivatives of the α‑amino groups of other amino acids could not be found. calculate the number of polypeptide chains in this protein. give the answer as a whole number.

What is the difference between the conducting zone and the respiratory zone of the respiratory system? the conducting zone is a series of cavities and tubes that move air to the respiratory zone where gases exchange with the bloodstream. the conducting zone exchanges gases between the lungs and the alveoli and the respiratory zone is a series of cavities and tubes that move air to the conducting zone. the conducting zone moves oxygen into the cells and the respiratory zone takes carbon dioxide away from the cells. the conducting zone moves oxygen into the bloodstream and the respiratory zone takes carbon dioxide away from the bloodstream.
