Question

genetic disease cytistic fibrosis includes deletion of 1 amino acid from the protein CFTR. W/o amino acid, CFTR cannt function because it.......

a. cannot carry oxygen

b. produces mucus

c. is folded in a way that is different from normal CFTR

d. has a different charge than normal CFTR

.... i think that the answer is C but am not so sure so please help

Answer 1

Is there an E "all of the above" b/c the change in the tertiary structure could also mean that it cannot carry O2. I also looked it up and y*d mucous is a side effect of CFTR. Different charge for D- I think also possible..

But usually mutations are about always folded different from original ones its just the function of the misfold that is the big dif. Can it still function prop. or not ??

Good luck
