OOL Follies: Evolutionists Ignore the Obvious QuestionsFebruary 20, 2013
By David Coppedge
In origin-of-life (OOL) research, any partial solution seems good enough, even if the big questions go unanswered.
Stack of Plates Sans Code
Science Now got real excited about a new kind of RNA that, with a sufficient kind of design, can organize into a stack that reporter Robert Service (not the Alaskan storyteller) believes mimics DNA. In “Self-Assembling Molecules Offer New Clues on Life’s Possible Origin,” he spoke of problems with certain RNAs called CA and TAP that stubbornly refuse to self-assemble in water. A little tweaking got them to cooperate the way scientists wanted:
Unfortunately, in water CA and TAP clump together in large ribbons and sheets and quickly fall out of solution, making it hard to conceive of how these proto-RNAs could have stored genetic information in the earliest stages of life.
Now, however, Hud and his colleagues at Georgia Tech and the Institute for Research in Biomedicine in Barcelona, Spain, have solved this solvent problem. The researchers gave TAP a short chemical tail, transforming it into a chemical they call TAPAS, as they reported on Friday in the Journal of the American Chemical Society. And that one change encourages it to assemble with CA to form rosettes in water. What is more, the rosettes stack atop one another, forming long genelike chains made up of as many as 18,000 individual TAPAS and CA components—quite a stack of small plates….
