Short tandem repeats Definitions:
Variations in length of genetic markers are called short tandem repeats (STRs). These are tandemly repeated units of two- to five-nucleotide sequences in specific regions of the genome.

When the repeat unit contains 2-5 nucleotides, the series of repeats is called a short tandem repeat, or STR.

Short tandem repeats Notes:
A short tandem repeat is a microsatellite, consisting of a unit of two to thirteen nucleotides repeated several to dozens of times in a row on the DNA strand. The number of these repeats is different for different people. The STR screening has found its application in many techniques including serving as a basis for identifying criminals based on sample collection from crime scene.
