“…This technique, developed by Williams et al (1990) and Welsh and McClelland (1990), is a powerful technique that involves the amplification of random segments of genomic DNA using Polymerase Chain Reaction (PCR). Since RAPD is simple, fast, and sensitive, it is now being used in many different fields, such as phylogeny, taxonomy, genotoxicity, and epidemiology (Marillia and Scoles, 1996;Fancelli et al, 1998). The results of RAPD allow the evaluation of how environmental pollutants modify the structure of DNA in living organisms (Conte et al, 1998;Zhiyi and Haowen, 2004).…”
