A group of investigators is studying a segment of the human genome that evidences an inter- individual variation in the number of nucleotides. They isolate a DNA segment of interest by running it on electrophoresis gel. They remove the portion of gel with the DNA and subsequently expose it to a labeled DNA probe. Which of the following laboratory techniques does this describe?
(A) Enzyme-linked immunosorbent assay
(B) Northern blot
(C) Polymerase chain reaction
(D) Sequencing
(E) Southern blot
(F) Southwestern blot
(G) Western blot
