DNA testing
Analysis of DNA (the genetic component of cells) in order to determine changes in genes that may indicate a specific disorder. DNA Profiling The analysis of short, highly specific, tandem-repeated—or hypervariable— genomic sequences, minisatellites known as variable number of tandem repeats (VNTRs), to detect the degree of relatedness to another sequence of oligonucleotides. This method of isolating and visualising of sequences of DNA was developed in 1984 by Alec Jeffreys, who identified minisatellites that do not contribute to gene function but are repeated in the genes and elsewhere in a DNA sample, thus providing highly specific information about that organism or person.
