. You obtain the DNA sequence of a mutant of a 2-kb gene in which you are interested and it shows base differences at three positions, all in different codons. One is a silent change, but the other two are missense changes (they encode new amino acids). How would you demonstrate that these changes are real mutations and not sequencing errors? (Assume that sequencing is about 99.9 percent accurate.)

Question
. You obtain the DNA sequence of a mutant of a 2-kb gene
in which you are interested and it shows base differences
at three positions, all in different codons. One is a silent
change, but the other two are missense changes (they encode new amino acids). How would you demonstrate
that these changes are real mutations and not sequencing errors? (Assume that sequencing is about 99.9 percent accurate.)
