Question

a mutation causes a substitution of one amino acid for another in the encoded protein. what type of mutation is th
nonsense
shift in reading frame caused by a deletion
silent
shift in reading frame caused by an insertion
missense

Explanation:

A missense mutation results in the substitution of one amino acid for another in the encoded protein. A nonsense mutation creates a premature stop codon. Silent mutations do not change the amino acid sequence. Insertions or deletions (unless in multiples of three) cause a shift in the reading frame, which typically leads to a completely different and often non - functional protein downstream of the mutation. Since the question specifically mentions substitution of one amino acid for another, missense is the correct answer.

Answer:

missense
