In related species there are few differences when you compare coding areas where are located de structural genes. For example betwenn the Chimpance and Humans , in this coding areas there are only about 2% of differences. Then the difference there are in non coding area where are located noncoding RNAs that now we know that are important in the regulation of expressions of the genes. In this last area also are located DNA of endogenous virus and transponibles elements that also have a specific functions.Enclosed I am sending 3 articles
