the cell, these machines cut, paste and genetic molecules, shut-tle nutrients around or turn them into energy, build and repair cellu-lar membranes, relay mechanical, chemical or electrical messages—n othe list goes on and on, and new discoveries add to it all the time. It is virtually impossible to imagine how a cell’ machines, which are mostly protein-based catalysts called enzymes, could have formed spontaneously as life first arose from nonliving matter around 3.7 billion years ago. To be sure, under the right conditions some build-ing blocks of proteins, the amino acids, form easily from simpler chemicals, as Stanley L. Miller and Harold C. Urey of the University of Chicago discovered in pioneering experiments in the 1950s. But Key conceptS

Researchers have found a way that the genetic molecule RNA could have formed from chemi-gigoing from there to proteins and enzymes is a different matter. A cell’s protein-making process involves complex enzymes pull-ing apart the strands of DNA’s double helix to extract the informa-tion contained in genes (the blueprints for the proteins) and translate it into the finished proct. Thus, explaining how life began entails a serious paradox: it seems that it takes proteins—as well as the in-formation now stored in DNA—to make proteins.

Other studies have supported the hypothesis that primitive would have been possible for genetic molecules similar to DNA or to cells containing molecules its close relative RNA to form spontaneously. And because these mol-similar to RNA could assemble ecules can curl up in different shapes and act as rudimentary catalysts, spontaneously, reproce and they may have become able to themselves—to reproce—with-evolve, giving rise to all life. out the need for proteins.
