Application questions
Can a protein be translated if a cell is defective for RNA
polymerase? Why or why not?
What would happen if the aminoacyl tRNA synthetase specific for
a tRNA carrying lysine were missing during translation? How would
this deficiency affect transcription?
What sequences are in DNA that are not found in the processed
mRNA?
What are the sequences that are in processed mRNA that are
translated into polypeptide?
Why would operating in a global (rather than a strictly
domestic) marketolace create a need for additional information for
managers? Discuss some of the additional information managers would
need and why such information would be valuable.
Cell Biology Short Answer Question:
Phospholipid biosynthesis at the interface between the ER and the
cytosol presents a number of challenges that must be solved by the
cell. Explain how each of the following is handled: 1) The
substrates for phospholipid biosynthesis are all water soluble, and
yet the end products are not. 2) The immediate site of
incorporation of all newly synthesized phospholipids is the
cytosolic leaflet of the ER membrane, and yet the phospholipids
must be incorporated into...
9. Explain what two types of proteins are transferred from the
cytosol to the ER. How are these proteins translocated into the
RER? What are some examples of proteins that would fit into each of
these two categories?
10. Explain the secretory and endocytic pathways.
11. Explain vesicle budding and protein coats. 12. Explain the
basic role of SNARES in vesicle docking.
13. Explain the types of covalent modifications of proteins in
the ER and Golgi. Relate these modifications to...
