Biology’s “dark matter”

Thanks to bioinformatics, researchers from the University of Lausanne have shed light upon a poorly understood category of genes, which produce long non-coding RNA molecules rather than proteins. A few of these genes appeared over 350 million years ago in the common ancestor of 11 species – amongst which humans, the great apes, opossums and frogs. The article was published in Nature, on 19 January 2014.
