In what way does a mutation in the DNA sequence affect the protein structure?
It does not affect the protein structure.
It always changes the protein's amino acid sequence.
It may change the amino acid sequence, leading to a different 3D shape.
It only affects the 3D shape of the protein.
Explanation
A change in the DNA sequence may result in a change in the amino acid sequence, which can affect the protein's shape and function.
