What is the effect of a missense mutation?

• they make the sequence stop early, creating a shorter protein

• they can create a different protein that might not work

• they make the same protein and work normally

What is the result of a nonsense mutation?

• the protein is not completed, and it creates only a fragment because it is stopped early

• there is no change to how the protein functions

• the substitution of a different amino acid caused the protein to be made incorrectly
