best_answer

A single nucleotide base in the DNA sequence of a gene can change in a point mutation, a form of mutation. The amino acid sequence of the protein that the gene codes for may vary as a result.

Frameshift mutations change the reading frame of the gene and the complete amino acid sequence downstream of the mutation by inserting or deleting one or more nucleotides.

A missense mutation is a type of mutation that alters the DNA sequence by one nucleotide, resulting in the incorporation of a different amino acid into the protein.

Silent mutation is a form of mutation that alters just one nucleotide in the DNA sequence without altering the protein's amino acid sequence.

Option 4 is the correct answer.
