DNA fragments formed from restriction enzyme digestion are called

Explanation:
Restriction enzymes cut DNA at specific sites to produce pieces called restriction fragments. When comparing different individuals, the lengths of these fragments can vary because of sequence differences that change where the cuts occur. Those length differences are known as Restriction Fragment Length Polymorphisms, or RFLPs. So the fragments produced by restriction digestion that show length variation and are used as genetic markers are referred to as RFLPs. The other terms don’t fit: alleles are gene variants, transposons are movable DNA elements, and vectors are vehicles used to carry DNA into cells.
