Quizplus · Accepted Answer

A DNA profile of an individual is typically generated by comparing banding patterns from 15 STRs (short tandem repeats) located on different chromosomes. This allows for a high level of accuracy in identifying an individual based on their unique DNA profile. PCR (polymerase chain reaction) is a technique used to rapidly replicate DNA segments, which can then be used for analysis, but is not typically used in generating DNA profiles for forensic purposes. Chromosome 7 does contain some STRs used in DNA profiling, but the profile is typically generated using STRs from throughout the genome.
