| Abstract | ||||
| A set of 2000 RAPD works involving different biological specimens was compiled and analyzed for the presence of discrete amplification to deduce the impacts of the percentage of nitrogenous bases (Guanine-Cytosine content) of RAPD markers on their discrimination of various biological specimens. Articles lacking data on RAPD amplification were excluded, while only 56 articles having a total of 761 decamer primers were subsequently subjected to logistic statistical analysis (Analysis of variance and correlation analysis). Results obtained revealed GC contents between 60-70%, 60-70%, 65%, 55% and 55-65% as the best for RAPD discrimination of bacteria, plants, insects, protozoans, and fungi, respectively. The bivariate correlation analysis also documents a significant relationship between GC contents of RAPD markers and their levels of polymorphisms. Our results, however, emphasize that the challenge faced with large-scale RAPD-PCR through several optimization techniques may be averted with judicious use of GC content as a predictor of the level of polymorphisms. | ||||
