- b. Compounds A, B, C, and D are known to be intermediates in the pathway for production of protein E. To determine where the block in protein-E production occurred in each individual, the various intermediates were given to each individuals cel Is in culture. After a few weeks of growth with the intermediate, the cells were assayed for the production of protein E. The results for each individuals cells are given in the following table. A plus sign means that protein E was produced after the cells were given the intermediate listed at the top of the column. A minus sign means that the cells still could not produce protein E even after being exposed to the intermediate at the top of the column. Denote the point in the pathway in which each individual is blocked.a. Compounds A, B, C, and D are known to be intermediates in the pathway for production of protein E.

There are different versions of trust1, all of which lead to different levels of the behavior associated with this neuropeptide on male behavior. Give some examples where it would be a good idea to know a particular males genotype-that is, which of the trust1 genes he has. Give an example of when you think science has gone too far and this information should not be known.
- Understanding the Relevance of Chaperones in Protein Folding Protein molecules, like all molecules, can be characterized in terms of general properties such as size, shape, charge, solubility/hydrophobicity. Consider the influence of each of these general features on the likelihood of whether folding of a particular protein will require chaperone assistance or not. Be specific regarding just Hsp7O chaperones or Hsp7O chaperones and Hsp60 chaperonins.Using the Nernst equation, calculate the equilibrium potential for Ca2 and for C1 from the following sets of data: a.
