Question

TAT is a codon for the amino acid tyrosine (Tyr).If a mutation changes TAT to TAA,what kind of mutation has occurred?

Quizplus · Accepted Answer

TAA is a stop codon, which means that the mutation changes TAT (which codes for tyrosine) into a premature stop codon. This causes the protein synthesis to end prematurely and produces a truncated protein, which could lead to a non-functional or dysfunctional protein. This type of mutation is called a nonsense mutation.
