... and appear near talomeres.(6) Microsatellites and Tetranucleotide / trinucleotide (STR's) repeats are other markers which can be used. The tandemly repeated consensus sequences are only two to five bases long. Compared to minisatellites, the shorter repeat lengths of STR markers make them more compatible with use of the Polymerase chain reaction (PCR). PCR is a way to amplify minute amounts of DNA. This advantage has made them popular and useful markers for recent genetic maps.(3), (2). The variation in length of the minisatellites is the basis of DNA fingerprinting. DNA fingerprinting is a way of identifying a person using the genetic material stored in the cells (particularly the nucleus within the cell where the DNA is found). DNA forensic analysis relies on one key characteristic of DNA: the configuration is the same in all cells of an individual. Altogether each person carries around 200,000 genes in each cell, comprising three billion "base ...
