Mutations in gene sequences are classified into a number of types. A frameshift mutation is a mutation that results in a change in the reading frame f the translation process. This means that it is most likely from the point of mutation, the translated product would be different from the original sequence. This is because frameshift mutations are caused by either a deletion or an insertion in the target DNA sequence.
Which of the following is the best example of a missense mutation?
A. Ala-Gln-Cys-Asp-Leu → Ala-Gln
B. Ala-Gln-Cys-Asp-Leu → Ala-Gln-Cys-His-Leu
C. Ala-Gln-Cys-Asp-Leu → Ala-Gln-Cys-His-Lys
D. Ala-Gln-Cys-Asp-Leu → Ala-Gln-Cys-Asp-Leu
