Satellite DNA is useful tool in 

  • Organ transplantation

  • sex determination

  • forensic science

  • genetic engineering


C.

forensic science

Britten and his coworkers (1996-68) have demonstrated that many vertebrate DNAs reassociate, especially, If broken into smaller pieces. This observation gave rise to the hypothesis that certain short sequences of bases are repeated hundred or more time in such DNAs. Such DNAs have been called repetitive or satellite DNAs have been called repetitive or satellite DNAs. All eukaryotes except years contain satellite DNA. Satellite DNA region like VNTR/RFLP are the basis of DNA fingerprinting (forensic science).
