D) fragment length polymorphisms
E) receptor proteins

Question

Quizplus · Accepted Answer

Restriction enzymes cut DNA at specific recognition sites, producing fragments of a predictable size. By using different enzymes to digest the DNA, the resulting overlapping fragments can be used to determine the sequence of the DNA molecule. This technique is called DNA sequencing.
