variation in the lengths of restriction fragments of DNA. These fragments are obtained from different individuals due to genetic polymorphism of the restriction sites in the chromosomes. It is also known as restriction fragment length polymorphism (RFLP).
a technique that uses electrophoresis to match DNA molecules to one another for identification purposes.
(or profiling) the use of biological residue found at the scene of a crime for genetic comparisons in aiding the identification of criminal suspects.
technique for identifying individuals, generally using repeated sequences in the human genome that produce a pattern of bands that is unique for every individual
The positive identification of an individual by matching specific DNA sequences, usually microsatellites, to a record of those known to belong to that individual (established through prior testing.)
A technique for identifying individual organisms based upon the uniqueness of their DNA pattern. The technique has applications in forensics, anthropology, conservation biology, and ecological research.
Apart from identical twins (which are natural clones) each person's or individual animal's DNA is unique. Analysis of this DNA, called DNA typing or DNA fingerprinting, can be used like fingerprints to identify individuals or distinguish between a range of suspects in a crime. The same technique can also be used to distinguish between otherwise indistinguishable animals and trace relationships.
DNA fingerprinting is a method used to identify individuals within a species. The DNA fingerprint itself is the individual-specific autoradiographic banding pattern (shown by electrophresis) that is produced when DNA is digested with a restriction endonuclease.
A pattern of DNA sequences, e.g. tandem repeat sequences, unique to an individual. This DNA `profile', which can be detected in minute amounts of cells (e.g. in blood or semen), can be used in criminal cases and paternity suits to establish identity.
Sequences of nucleic acids in specific areas on a DNA molecule are polymorphic, meaning that genes in those locations may differ from person to person. DNA fragments can be cut from those sequences using restriction enzymes.
Français] A method to isolate and create images of DNA sequences. The image created is an identification aid for organisms similar to that of taking human fingerprints.
Identification of the DNA of different individuals based on variation that exists between them in the sequence of bases in the DNA.
the technique that identifies the unique pattern of DNA fragments in an organism.
A method of forensic analysis that compares fragments of DNA between to distinguish between different individuals.
Analyses of the lengths of the fragments reveal that when looking at multiple VNTRs within and between individuals, no two people have the same assortment of lengths. This technique became known to the public as "DNA fingerprinting" because of its powerful ability to discriminate between unrelated individuals.
The use of restriction enzymes to measure the genetic variation of individuals. This technology is often used as a forensic tool to detect similarities in blood and tissue samples at crime scenes. In the cattle business, this technology is used to verify the parentage of individual animals.
the use of fragments of DNA to identify the unique genetic makeup of an individual. There are the RFLP method and the PCR method.
A laboratory method for graphically characterizing an individual's DNA, creating a unique genetic "fingerprint."
a unique pattern of dna fragments as revealed by southern hybridization or by the polymerase chain reaction.
a DNA analysis method that measures genetic variation among individuals. This technology is often used as a forensic tool to detect differences or similarities in blood and tissue samples at crime scenes.
The use of DNA sequences specific for an organism for identification purposes.
DNA fingerprints are sequences of DNA molecules (genetic material) that are unique to each individual organism
A process which uses fragments of DNA to identify the unique genetic makeup of an individual.
Detecting patterns in DNA that indicate the presence of a gene for a trait. The pattern resembles a bar code printed on a commercial product so computers can scan the price. Forensics experts can use this distinct pattern to link or clear an Individual suspected of being involved in a crime, like they compare fingerprints. Breeders can use these patterns to find and select breeding stock with traits such as disease resistance.
A laboratory technique in which the banding patterns of DNA fragments from two different individuals are compared. ()
Forensics]. DNA, the substance that carries hereditary patterns from one generation to the next, is unique to every individual and thus can be used, like fingerprints, to positively identify a person.
In genetics, the identification of multiple specific alleles on a person's DNA to produce a unique identifier for that person. Source : Human Genome Project Information
