Correct answer: It would create different sized fragments and alter the banding pattern.

Explanation: A mutation that removes or creates a restriction enzyme recognition site changes where the enzyme cuts the DNA, so the resulting fragments are different sizes and the RFLP/DNA fingerprint banding pattern on a gel changes. It does not prevent DNA extraction or stop gel electrophoresis from working. (If only one chromosome carries the mutation, you may see a mixture of the original and altered bands.)
