DNA can be divide into fragments using restriction enzymes.
(a) Outline the technique used to separate these fragments.
(b) What property of the DNA fragments permits this separation?
a) DNA fragments, in solution, are placed at one end of a sheet of gel and an electric current is applied which separates the fragments.
(b) The size of the fragments verifies how rapidly they move through the gel. Smaller fragments travel faster and further than larger fragments
