ABSTRACT
A DNA segment that appears more than once on the same chromosome is known as a repeat. Human genomes contain 5-10% of such repetitive sequences that occur in tandem or adjacent to each other. These repetitive sequences vary in size and length and show sufficient variability among individuals in a population. Regions of DNA that contain these short repeated segments are referred to as short tandem repeats (STRs) and are important markers for human identity testing in the forensic community.
