He says this idea has «very profound» implications for the debate over the origins of bacterial genes that are present in the human genome but absent in our closest relatives (Science, 8 June, p. 1903): The amount of conjugation Waters detected is «high enough to readily explain» the possible infiltration of bacterial genesinto our DNA, meaning that conjugation could have happened quickly enough to add genes only to humans, in the years since they split from the common ancestor they shared with chimpanzees.

Further, he added, «knowing these genes may help us to understand how IBD occurs in humans, and how to treat it.»

The experiment's final product is equivalent to the naturally occurring genetic code of M. genitalium, with two minor exceptions: The scientists disabled the gene that gave the bug power to infect human cells, and they added a few «watermarks,» short strips of signature genetic code that identify the product as man - made.

It's the study of how information is added onto or influences the read - out of genes and, Feinberg says, is not combined often enough with genetics research to understand human disease.
