JUNK DNA: NOT SO JUNKY AFTER ALL

摘要

Microsatellites, or simple sequence repeats, are considered to be junk DNA. Yet their exploitation in DNA profiling techniques has expanded the repertoire of useful sequences for plant biologists. Some old and new techniques involving microsatellites are portrayed, such as microsatellite fingerprinting, microsatellite primed polymerase chain reaction (PCR), anchored microsatellite primed PCR, random amplified (microsatellite) polymorphic DNA (RAPD) analysis, the generation of microsatellite fingerprints in RAPDs and the production of sequence tagged microsatellite sites.
