Only a small sample of cells is needed for DNA fingerprinting. A drop of blood or the root of a hair contains enough DNA for testing. Semen, hair, or skin scrapings are often used in criminal investigations. A person who has DNA fingerprinting done voluntarily usually provides a sample of blood taken from a vein.
In conventional DNA fingerprinting, hypervariable and repetitive sequences (minisatellite or microsatellite DNA) are detected with hybridization probes.As demonstrated here, these probes can be used as single primers in the polymerase chain reaction (PCR) to generate individual fingerprints.n conventional DNA fingerprinting, hypervariable and repetitive sequences (minisatellite or microsatellite DNA) are detected with hybridization probes.
