Which of the following is TRUE regarding restriction fragment length polymorphisms (RFLPs)?

Question

Quizplus · Accepted Answer

RFLPs are variations in the lengths of DNA fragments that are generated when a particular region of the genome is cut with a restriction enzyme. These variations arise from differences in the DNA sequence, which may create or abolish recognition sites for the restriction enzyme. Therefore, option A is true. Option B is incorrect as there are other methods to distinguish between identical twins, such as analyzing variable number tandem repeats (VNTRs) or short tandem repeats (STRs). Option C is also incorrect as RFLPs can arise from a variety of genetic variations, not only chromosomal mutations. Option D is incorrect as RFLPs are used as a tool to study genetic variation and relationships between individuals or populations, not for gene transfer.
