Recently it was discovered that the bacteriophage M13 contains in its protein III gene, tandem repeats of a 15-bp motif that can recognize a family of hypervariable minisatellites in vertebrate DNA (1). Southern blots of human DNA digested with Hae III and probed with 32p_i aD eled M13 revealed complex individual-specific DNA fingerprints, similar to those(More)
