The question I encountered asks about which kind of mutation happened that would make cause a lack of 50 amino acids near the C terminus. The possible answers were
missense mutation
back mutation
a sense mutation
frameshift mutation
The answer was frameshift mutation because the addition or deletion of a base could lead to creation of stop codon causing deletion of the 50 amino acids in the chain. However, why could it not be a missense mutation? Can't the missense cause one amino acid to become a stop codon instead?
