Evaluation of a link between STRs and TIS selection on the genomic DNA (a) and cDNA (b) platforms. The Fisher exact test statistic value < 0.00001. The number of times in which human-specific and non-specific STRs occurred with homologous and non-homologous TISs in other species is counted. %Similarity was checked for the first five amino acids (excluding the initiating methionine) of all annotated proteins for the orthologous genes in 46 species. TIS = translation initiation site. STR = short tandem repeat
