Human gut parasite has a sinister use for its stolen genes

It is well established knowledge that bacteria routinely exchange genes between unrelated species, creating an extensive network of information flow independent of sexual reproduction. By acquiring new genes, each being a blueprint for a single protein, the bacteria gain also the functions the proteins perform... click to read more

Symbiogenesis: how algae and bacteria shaped new genes together

Genes are an essential component of every living being. They are encoded in the DNA, and contain the information needed to produce a fully-functional organism. Deciphering the origin of new genes in organisms is important to understand how living beings adapted to their environment. Genes... click to read more
