A biosynthetic error in reading the genetic code gives rise to an enzyme that folds in an abnormal manner.Which of the following is most likely to happen to this enzyme?
a denaturation and refolding
b faster degradation
c inactivation by phosphorylation
d tansportation out of the cell via the golgi complex
A 66year old man who is undergoing chemotherapy for lekumia has a 3 day history of progressive fever,headache,nausea, and deteoration of mental acuity.analysis of csf shows lymphocytic pleocytosis,a normal glu conc. , and a slightly increased protein conc..The causual agent is presumptively identified by a positive Indian ink test and later confirmed with culture Which of the following is the major virulence factor of the infecting organism producing this disease?
a antigenic variation
b exotoxin
c Ig protease
d leuckocidin
e polysaccharide capsule
