A change occurs in one nucleotide of a triplet within a protein-coding portion of a gene. This change results in a new triplet that codes for a stop codon. What is this mutation called? - -Nonsense mutation A point mutation occurs in which a single nucleotide change results in a codon that codes for a different amino acid. What is this mutation called? - -Missense mutation A single nucleotide is changed. What is this mutation called? - -Point mutation A point mutation occurs in which a sin...
