"In Denmark, Dr. Rasmussen is seeking to design the most stripped-down minimalist suggestion of a functioning cell. As he sees it, there are three basic capacities that a living cell must possess. It must have a means of channeling free energy in the environment to meet its demands: that is, it must have some form of metabolism. It must have an enclosure: a cell membrane. And it must have the informational wherewithal to reproduce itself: a genome. Dr. Rasmussen and his co-workers have devised reasonable if crude facsimiles of the three cellular non-negotiables, and they’ve managed to merge two of them together in any given experiment — and in one case even all three of them. The goal of contriving a self-replicating and autonomously metabolizing protocell, however, continues to elude them. “We have the instruments,” he said, “but it doesn’t sound like an orchestra yet.”"
