In the mating Hfr Strs met+ his+ leu+ trp+ Ala+ X F- Strres met- his- leu- trp- Ala-. At regular interval time, the mating cells are interrupted and the cell suspensions plated on four different growth media with streptomycin. The amino acids in the growth media and the number of colonies observed on each are as follows:

An otherwise healthy student in your class is infected with EBV, the virus that causes infectious mononucleosis. The same student had already been infected when she was a child, and she had merely experienced a mild sore throat and swollen lymph nodes in her neck. This time, though infected, she does not get sick.
Her immune systemʹs recognition of this infection will involve which of the following?

When stress conditions arise, or when protein synthesis threatens to overwhelm the protein-folding capacity of the ER, unfolded proteins can accumulate. These conditions trigger the unfolded protein response (UPR)
a) unfolded protein response ensures to reduces the rate of protein synthesis by mTOR pathway
b) Amyloid aggregates that form before the UPR can come into play may be removed. Some are degraded by autophagy
c) Amyloid aggregates that can be removed by other mechanism such as lysosomal degradations
d) UPR also bring the various systems into alignment by increasing the concentration of chaperones in the oxygen deprived conditions
Which of the following statements would be incorrect?
