Quizplus · Accepted Answer

Mutations that destroy or create a cleavage site for a restriction enzyme are responsible for creating different sizes of DNA fragments, which are detected through gel electrophoresis as restriction fragment length polymorphisms (RFLPs). Therefore, choice B is the best answer. Variable number tandem repeats (VNTRs) are caused by differences in the number of repeats of short DNA sequences between individuals, while single-nucleotide polymorphisms (SNPs) involve variation in single bases. Copy-number variants (CNVs) refer to differences in the number of copies of a particular DNA segment. While mutations may contribute to some CNVs and SNPs, these do not specifically involve the creation or destruction of a cleavage site for a restriction enzyme.
