what is str dna profiling What is STR profiling STR profiling is an analytical DNA technique which PCR amplifies variable microsatellite regions from a genomic DNA template separates the PCR amplicons
The most common type of DNA profiling today for criminal cases and other types of forensic uses is called STR short tandem repeat analysis Using DNA to distinguish between two individuals is a tricky matter because STRs occur when a short sequence of DNA is repeated multiple times in a row for example a triplet repeat such as CAG STR testing is used to diagnose conditions that are predominantly

STR short tandem repeat analysis determines a person s DNA profile by establishing how many times a DNA sequence called a short tandem repeat unit appears in a chromosomal location The chromosomal location STR DNA profile analysis involves the simultaneous amplification of STR markers plus a locus for gender determination The amplicons from the PCR are resolved by capillary electrophoresis and sized
Short tandem repeats STRs are repeated segments of DNA that are typically 2 6 base pairs in length These STRs are scattered throughout our genome At each of the tested genetic sites one STR allele comes from the mother and STR or short tandem repeat refers to a DNA method that uses discrete targeted PCR primers to amplify specific regions of interest in the genome based on sequence homology to the primers
