Aside from genetic determination for father-child purposes, the Deoxyribose Nucleic Acid tests can be used to pinpoint the suspect in any crimes.
This is based on the principle that flecks of skin, hair or body fluid have been left in the crime scene by the suspect so if these DNA profile matches the ones obtained from that person, it is very likely that the right person will be prosecuted.
Forensic DNA fingerprinting is performed by qualified forensic scientists through series of tests.
To identify an individual, 13 DNA regions are scanned.
These loci vary from person to person so they can be utilized to create a DNA profile or fingerprint.
With the 13 regions defined, there us extremely a slim chance to have another person possessing the same genetic profile.
DNA typing involves getting samples from blood, body tissue, bone, hair or body fluid from the scene of the crime.
Then, these are analyzed for the presence of a set of specific DNA markers.
Scientists particularly design small pieced f DNA probes that will each look for and attach to a complementary DNA arrangement in the sample.
Series of probes bonded to a DNA sample will form a specific pattern for an individual.
These profiles are compared to a suspect's personal sample.
If 4 to 5 regions are alike, the suspect is likely the one who left the sample in the crime scene.
The 4 to 5 region comparison is based on the premise that only one-tenth of a single percentage of DNA (which is about 3 million bases) vary from one person to another.
Forensic DNA fingerprinting has been considered by judges to be better than eyewitness accounts since physiological evidence can never lie.
Though DNA testing is not 100 percent sure all the time because of similarities in specie genetic traits, it still remains as a powerful tool to pinpoint the actual criminal.
Aside from the crime-related issues solved, this procedure can also be used to identify endangered and protected species to prosecute poachers, detect bacterial or other air, water, soil and food contaminants.
It can also match organ donors with recipients, recognize pedigree for seed or livestock breeds as well as authenticate wines, caviars and other consumables.
Indeed, forensic DNA fingerprinting is a breakthrough of the century.
