Warm Up 1/10 What type of mutation results in a stop codon?

**nonsense mutation** results in a stop codon. This type of mutation changes a codon that originally coded for an amino acid into one of the three stop codons (UAA, UAG, or UGA in RNA, and TAA, TAG, or TGA in DNA). This prematurely terminates translation of the mRNA, resulting in a truncated and often non-functional protein.
