||"A first systematic survey of gene strand bias showed that genomes could
have from 55 to 80% of genes in the leading strand, although systematically more than 85 % of ribosomal proteins were coded in the leading strand of these genomes (McLean
et al., 1998). In fact, 78 % of the genes of Firmicutes (including mycoplasmas) are in the leading
strand, compared with 58 % for the other genomes (primary source)."
