Question

If a FRAMESHIFT mutation causes a stop codon to be inserted into the DNA sequence a the resulting protein may be too short and non-functional b the resulting protein may be too long and non-functional c the phenotype and genotype for the gene will remain unchanged d the resulting protein will not be affected

Answer 1

A frameshift mutation alters the reading frame of the entire protein-coding sequence, which can lead to significant changes in the amino acid sequence of the resulting protein. If a stop codon is inserted into the sequence because of a frameshift, the translation will terminate prematurely, resulting in a truncated protein.

Therefore, the correct answer is:

a) the resulting protein may be too short and non-functional.
