Microsatellites consist of tandemly repeated sequence, no more than 6 bases long. They are scattered throughout most eukaryotic genomes. The major characteristic that makes microsatellites as useful and powerful genetic tool is the extensive length polymorphism that first of all reflects allelic variation in the number of the tandemly arranged perfect repeats. Microsatellite are generally considered as the most powerful genetic marker.
A genetic marker is a gene or DNA sequence with a known location on a chromosome that can be used to identify individuals or species. Genetic marker that reveal polymorphisms at the DNA level are called molecular marker.
Molecular markers are called as DNA markers, which should be thought of as signs along the DNA trail that pinpoint the location of desirable genetic traits or indicate specific genetic differences.They are responsible for various neurological diseases and hence the same cause can now be utilized for the early detection of various diseases, such as, Schizophrenia, Bipolar Disorder and Congenital generalized Hypertrichosis. These agents are widely used for forensic identification and relatedness testing, and are predominant genetic markers in this area of application.
