Quote:Meanwhile, back on Earth at the MRC Laboratory of Molecular Biology in Cambridge, UK, have created synthetic molecules that copy genetic material. The enzyme, tC19Z, that has been synthesised could be an artificial version of one of the first enzymes that ever existed on our planet three billion years ago -- and a clue to how life itself got started. Their goal is to create fully self-replicating RNA molecules in the lab.
