Answer:
C)frame-shift
Explanation:
Since the protein-encoding DNA is divided into codons of three bases each, insertions and deletions can alter a gene to the point that its message loses its meaning. These changes are called the reading frame offset.
For example, consider the phrase: "The fat cat sat". Each letter represents a codon. If we delete the first letter and try to analyze the sentence in the same way, it doesn't make sense. In frame-shift, a similar error occurs at the molecular level, causing the codons to be analyzed incorrectly. This usually produces useless proteins.
