DNA was isolated from a patient and cut with HaeIII. The resulting fragments were separated by gel electrophoresis and transferred to a membrane. The fragments were allowed to hybridize to a probe, and the resulting band pattern was compared with that seen in another sample of DNA. Which of the following methods is described?

The method described involves isolating DNA, cutting it with a restriction enzyme, separating the fragments by gel electrophoresis, transferring the fragments to a membrane, and hybridizing the fragments to a probe. This is the method used in RFLP analysis by Southern blotting. VNTR analysis by PCR involves amplifying a short tandem repeat region of DNA and comparing the resulting band pattern, while SNP analysis involves sequencing specific sites of variation in the genome. STR analysis by PCR also involves amplifying short tandem repeat regions of DNA, but it typically uses different primers and conditions than VNTR analysis.
