DNA Mutations

Question 4 • LHS Biology 1

A scientist discovers a mutation that changes one amino acid in a protein. AI modeling predicts that the protein's shape changes significantly. What conclusion is best supported?

Answer
A
The mutation will stop ribosomes from translating RNA into proteins.
B
The mutation will cause the protein to break into smaller molecules.
C
The mutation will cause the protein to break into smaller molecules.
D
The mutation may affect the protein's ability to function by changing its shape.

Explanation

A protein’s shape helps determine how it works, so a significant shape change may affect its function. The evidence supports a possible effect, not certainty that translation will stop or that the protein will break apart. Choice D is the best-supported conclusion.
