Hi sorry but i don't have an idea but i know that a dna profile is based on fingerprints I'm not exactly sure have a nice day
The likely causes of the abnormal protein could be, both choice 1 and choice 2. Both are pretty similar in their consequence, since they describe a mutation which either keeps RNA polymerase to keep going after it usually stops or the stop codon, is not a stop site anymore. This causes are well documented and some of them are causes of illness. The third option, although feasible, it would find many obstacles, since introns would be hard to traduce. So, to sump up, choice 1 and choice 2 are the correct options.
The answer is A hope I helped !!
