Variable tandem repeats and restriction fragment length polymorphisms (RFLPs) are synonymous-both consist of repeated fragments of DNA with the same sequence (i.e., GTAGTAGTA).

Question

Quizplus · Accepted Answer

Variable tandem repeats (VNTRs) and RFLPs are not synonymous. VNTRs are stretches of repeated DNA sequences that vary in length between individuals, whereas RFLPs are differences in the length of DNA fragments that are cut by restriction enzymes. While both types of DNA markers can be used for genetic testing, they are not interchangeable.
