Textbook Question
Chapter 4, Problem 12TYU
INTERPRET data An investigator has isolated two mutant strains of yeast that fail to secrete a short polypeptide. She fractionated the cells and compared the concentrations of this polypeptide in the different cellular fractions with those found in normal cells. What point in the secretory pathway would you expect would be defective for mutant a and mutant b?

Talk about a antibiotic that inhibits bacteria by inhibiting protein synthesis. Explain how these antibiotics interact with the protein synthesis machinery; what part of the protein synthesis machinery do they bind, and do all of these antibiotics bind to the same part of the machinery? How does this work to stop protein synthesis? Explain how it halts protein synthesis. Are these antibiotics bacteriostatic or bactericidal. Why and what does that mean for therapy?

Fill in the Blank: If you observe mice or humans with muscle contraction problems (including muscular dystrophy), then you can say that their muscle cells have their intermediate filament _________________ mutated.a) desmin
b) vermin
c) nestin
d ) gremlin
Fill in the Blanks: The building blocks of our cell proteins are called _____________________ ; and the number of different types of these building blocks are _____ .a) lipids ; 10
b) amino acids ; 20
c) nucleotides ; 30
d) nucleic acids ; 3010.
A. Dr. Randy Schekman introduced you to a yeast model system for studying membrane fusion and vesicle trafficking. Imagine that you have isolated a new temperature-sensitive sec mutant which you suspect has a specific defect in secretory vesicle docking and fusion with the plasma membrane (exocytosis). Describe an experiment you could do to test your hypothesis.
B. Now, explain how you would continue your experiment to identify which secretory pathway proteins are present on these secretory vesicles.
C. Finally, among the proteins present in these synaptic vesicles according to mass spec you find a protein which contains a G-domain fold suggesting that it is a G-protein. Briefly outline how, in principle, you would determine which of the other proteins is a GAP for this G protein.

What is the most likely effect of losing this domain on the cell's ability to bind? A It would affect the cell's ability to attach to the ECM. B It would have no effect on the cell's ability to attach to anything. C It would affect the cell's ability to attach to the cytoskeleton through adaptor proteins. D It would affect both the cell's ability to attach to other cells and the cell's ability to attach to the cytoskeleton.arrow_forwardYeast cells are eukaryotes, and they require a functional secretory pathway to grow and to maintain cellular organization. But surprisingly, when SRP is removed from yeast cells by deleting the relevant genes, the cells are still alive (although they grow slowly). a) How can yeast survive without SRP?

Gut granules are a type of lysosome-related organelle (LRO) uniquely found in the intestinal system of C. elegans from early embryonic development to adulthood. Whereas lysosomes facilitate digestion of materials, LROs are more diverse in their functions, due to the different factors (proteins, chemicals, etc.) contained in the LRO. To achieve the unique compositions of molecules in LROs, identify which kind of transmembrane transport must be employed at some point in LRO biogenesis: passive transport (facilitated diffusion) or active transport.
