Final answer:
A frameshift mutation occurs when extra base pairs are added or removed from a gene, resulting in a shift in the reading frame. In the given gene sequence ATCTAGGTACTA, the correct frameshift mutation would be option C. ATCATGGATCTA.
Step-by-step explanation:
A frameshift mutation occurs when extra base pairs are added or removed from a gene, resulting in a shift in the reading frame. This can have significant consequences on the subsequent codons and may create stop codons.
In the given gene sequence ATCTAGGTACTA, the correct frameshift mutation would be option C. ATCATGGATCTA. This sequence represents a deletion of one nucleotide, causing a shift in the reading frame and altering subsequent codons.
