Question

the diagram below illustrates types of point mutations. which type of point mutation will result in a stop codon, which halts the production of proteins? click the name of the mutation.

Explanation:

A nonsense mutation occurs when a single - base substitution changes a codon for an amino acid into a stop codon. In the given diagram, at the mRNA level, the codon changes from a normal amino - acid - coding codon (in this case, the original DNA “TTC” transcribes to mRNA “AAG” which codes for Lys, and in the mutation, the DNA “ATC” transcribes to mRNA “UAG” which is a stop codon). This premature stop codon halts protein synthesis.

Answer:

Nonsense mutation.
