Evidence of ribosomes. Evidence of mRNA. BIOL 1010 Section B Fall Midterm Test 6 21. The bacterial flagellum differs from the eukaryotic flagellum in all the following ways, EXCEPT: A. Bacterial flagella are much smaller than eukaryotic flagella. B. Motion is caused by a rotational motor at the base of the bacterial flagellum; in eukaryotes, motion occurs as a result of the sliding microtubules and motor proteins. C. Bacterial flagella usually have a “9 + 2 complex” arrangement; eukaryotic flagella usually have a different complex arrangement. D. The proteins involved in each structure are very different (as are the genes that encode them). 22. Cells of the pancreas will incorporate radioactively labeled amino acids into proteins. This "tagging" of newly synthesized proteins enables a researcher to track their location. In this case, we are tracking an enzyme secreted by pancreatic cells. What is its most likely route? A. B. C. D. E. Endoplasmic reticulum → Golgi → nucleus Golgi → endoplasmic reticulum → lysosome nucleus → endoplasmic reticulum → Golgi Endoplasmic reticulum → Golgi → vesicles that fuse with plasma membrane Endoplasmic reticulum → lysosomes → vesicles that fuse with plasma membrane 23.
