Question

Quizplus · Accepted Answer

A mutation that changes the DNA sequence and substitutes one amino acid for another in a way that affects the encoded protein's functioning can cause disease. This is because the altered protein may not be able to perform its normal function, leading to a disruption in cellular or bodily processes. Options A, C, and D do not necessarily result in a disease-causing mutation.
