Question

question: what is the best explanation for the difference between the missense and nonsense mutations in the graph? (2 points) missense mutations change one amino acid, possibly reducing protein function, while nonsense mutations create a premature stop codon that prevents full protein production. missense mutations remove the protein’s start codon, while nonsense mutations only change one amino acid. both mutation types change the protein shape in exactly the same way. missense mutations always increase protein production, while nonsense mutations always decrease it.

Explanation:

Missense mutations substitute one amino - acid in a protein sequence, which may affect protein function. Nonsense mutations introduce a premature stop codon, halting protein synthesis prematurely.

Answer:

Missense mutations change one amino acid, possibly reducing protein function, while nonsense mutations create a premature stop codon that prevents full protein production.
