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