A scientist isolates two specific mRNAs. One codes for the enzyme fowlase, an enzyme that is involved in digestion in chickadees; the other codes for the quail enzyme quailase that is involved in cellular carbohydrate metabolism. Both mRNAs are placed in a test tube with RER vesicles stripped of their ribosomes, free ribosomes and precursors for protein synthesis. When the protein synthesis reaction is complete, fowlase is found inside the vesicles; quailase is found in the liquid portion of the test tube outside the vesicles. What can one conclude about the two proteins
