WebOct 4, 2024 · A deletion mutation is the opposite; it occurs when a base pair is deleted from a sequence. These two types of point mutations are grouped together because both of them can drastically affect the sequence of amino acids produced. With one or two bases added or deleted, all of the three-base codons change. This is called a frameshift mutation.
