Missense mutations are changes in DNA that result in the substitution of one amino acid for another in a protein. While they may affect protein function, they are often nonlethal and can remain in the gene pool, potentially driving evolution. Nonsense mutations result in a premature stop codon and are likely to be lethal or severely impair protein function. Frameshift mutations involve the insertion or deletion of nucleotides, resulting in a misreading of the genetic code and most likely causing a nonfunctional protein. Deletions involve the loss of one or more nucleotides and can also lead to nonfunctional proteins.
