B.sex determination
C.forensic science
D.genetic engineerings
Solution
Britten and his coworkers (1966-68) have demonstrated that many vertebrate DNAs reassociate, expecially if broken into smaller pieces. This observation gave rise to the hypothesis that certain short sequence of bases are repeated handred or more times in such DNAs. Such DNAs have been called repetetivie or satellite DNAs. All eukaryotes except years contain satellite DNA. Satellite DNA regions like VNTR / RELP are basis of DNA fingerprinting (forensic science).
