Final answer:
Frameshift mutations can have a drastic effect on the encoded protein. While intragenic suppressor mutations can compensate for some mutations, it is unlikely that they can suppress frameshift mutations.
Step-by-step explanation:
Frameshift mutations occur when there is an insertion or deletion of nucleotides in a DNA sequence that is not a multiple of three. These mutations can lead to a shift in the reading frame and alter the entire protein sequence encoded by the DNA.
Intragenic suppressor mutations occur within a gene and can sometimes compensate for the effects of another mutation. However, frameshift mutations are generally more severe and disruptive to the protein sequence than other types of mutations. Therefore, it is unlikely that intragenic suppressor mutations can completely suppress the effects of frameshift mutations.
To summarize, frameshift mutations can have a drastic effect on the encoded protein, and while intragenic suppressor mutations can compensate for some mutations, it is unlikely that they can suppress frameshift mutations.
