please answer all that you can 1. You have genetically engineered green fluorescent protein (GFP) containing a KDEL sequence (GFP-KDEL). When GFP-KDEL is expressed in normal human fibroblasts and examined using fluorescence microscopy, the fluorescence appears diffuse across the cytoplasm. How would you explain this observations given that KDEL is supposed to be an ER-specific sorting sequence? A. This engineered GFP would not have a hydrophobic signal sequence to get it into the RER in the first place. B. The...
Chapter 4: A Tour of the Cell 5. Smooth endoplasmic reticulum (SER) lacks _, which gives it a "smooth" appearance. 6. True or false: If false, make it a correct statement. The smooth endoplasmic reticulum con- tains many enzymes that allow it perform functions like detoxify circulating drugs. 7. Use Figures 4.14 (page 65 of your textbook) and 4.17 (page 67 of your textbook) to answer the following question. Place the following steps in the order in which they occur...
