Though the average bacterium has fewer than 5, 000 genes, compared with around 20, 000 protein-coding genes in the average mammal (bacteria do not go in much for RNA-only genes), there are lots of species of bacteria.

ECONOMIST: Inhuman genomes

This vast majority of genetic material known as functional noncoding DNA, mostly embedded within and around the genes, was thought to play an important but murky role in regulating how the coding genes go about their business.
