Same question. How could you determine between the specific nerve roots (C7 vs. C8)?
Someone I was talking to (and post below) was saying that first aid mentions triceps is C7, so that's what should've been the big thing for us.
you might see some ulnar nerve involvement if C8 was involved her
I chose nonsense because I thought it'll make the enzyme shorter (since less bonds = more heat liable = can't work at 42 degrees) but yea, probably won't work even at 30 if it's an early nonsense.
A good clinically related example is HbC disease on electrophoresis. HbC disease is due to a missense mutation (glutamic acid (-) for valine (neutral)). The mutated hemoglobin is still fairly functional but when placed on gel electrophoresis the HbC migrates the least far from the negative electrode due to less negative propulsion (lack of wild type glutamic acid).
