Why RNA is right-handed

From Quanta Magazine:

Joyce and others suspect it’s simply chance.

Actualy, they don’t susect that; they know that. It is the one thing they truly know. Everything else is “nearly,” “possibility,” and “close.”

Joyce remains interested in making life from scratch. Everything else, including the chirality problem, is just a hurdle toward that larger prize, he said.

The new ribozyme may provide the best shot yet. It nearly fulfills the most basic properties of life — the ability to replicate and to evolve. “They went so far as to show the mirror image can copy itself,” Chaput said. “That gets very close to replication.” The next step will be to make that happen iteratively. “If you look in the mirror, make a copy, then put yourself in the mirror, and make a copy of the person in the mirror, then you have replication,” Chaput said.

That iterative process opens the possibility for evolution, as mistakes made during copying will allow the molecule to evolve new traits. “The real key to all of it has been setting up a system in the lab capable of evolution on its own,” Unrau said. “Jerry is close.”

We are always “close” to “ capable of evolution on its own.”

Quest, one thing about quantum mechanics is that it, with quantum non-locality, refutes the old 'the universe is a closed system' argument of materialists. Dr. Gordon puts it like this: BRUCE GORDON: Hawking’s irrational arguments – October 2010 Excerpt: ,,,The physical universe is causally incomplete and therefore neither self-originating nor self-sustaining. The world of space, time, matter and energy is dependent on a reality that transcends space, time, matter and energy. http://www.washingtontimes.com/news/2010/oct/1/hawking-irrational-arguments/ And with the refutation of that false 'closed system' belief, there is no reason that God cannot create animals or humans. In fact, on materialism, we would expect things to be randomly 'popping into' and out of existence all the time Multiverse and the Design Argument - William Lane Craig Excerpt: Roger Penrose of Oxford University has calculated that the odds of our universe’s low entropy condition obtaining by chance alone are on the order of 1 in 10^10(123), an inconceivable number. If our universe were but one member of a multiverse of randomly ordered worlds, then it is vastly more probable that we should be observing a much smaller universe. For example, the odds of our solar system’s being formed instantly by the random collision of particles is about 1 in 10^10(60), a vast number, but inconceivably smaller than 1 in 10^10(123). (Penrose calls it “utter chicken feed” by comparison [The Road to Reality (Knopf, 2005), pp. 762-5]). Or again, if our universe is but one member of a multiverse, then we ought to be observing highly extraordinary events, like horses’ popping into and out of existence by random collisions, or perpetual motion machines, since these are vastly more probable than all of nature’s constants and quantities’ falling by chance into the virtually infinitesimal life-permitting range. Observable universes like those strange worlds are simply much more plenteous in the ensemble of universes than worlds like ours and, therefore, ought to be observed by us if the universe were but a random member of a multiverse of worlds. Since we do not have such observations, that fact strongly disconfirms the multiverse hypothesis. On naturalism, at least, it is therefore highly probable that there is no multiverse. — Penrose puts it bluntly “these world ensemble hypothesis are worse than useless in explaining the anthropic fine-tuning of the universe”. http://www.reasonablefaith.org/multiverse-and-the-design-argument The Absurdity of Inflation, String Theory and The Multiverse - Dr. Bruce Gordon - video http://vimeo.com/34468027 Here is the last power-point slide of the preceding video: The End Of Materialism? * In the multiverse, anything can happen for no reason at all. * In other words, the materialist is forced to believe in random miracles as a explanatory principle. * In a Theistic universe, nothing happens without a reason. Miracles are therefore intelligently directed deviations from divinely maintained regularities, and are thus expressions of rational purpose. * Scientific materialism is (therefore) epistemically self defeating: it makes scientific rationality impossible. bornagain77
OK, BA77...Can you think of a way how The Designer could have used quantum physics-quantum mechanics to create life in the full form...such as a human or an animal...? Quest
See Paramecium bursaria
So if we start we eukaryotes symbiosis will get to eukaryotes? Geez Zachriel, humans have billions or trillions of symbiotic prokaryotes. Does that mean endosymbiosis for the origin of eukaryotes is battle tested? Dr Sagan's concept only applied to organelles and not the nucleus and as such doesn't get to eukaryotes anyway. Joe
Quest: How are they going to get to eukaryotic cell since endosymbiosis only exist in science fiction books..? See Paramecium bursaria. Zachriel
keith s, This challenge is also for you... don't disappoint this time again... Quest
OK... Who likes quantum mechanics...? Anybody here except BA77...? I would like to theorize about the creation of life... but I need keith s to commit to it... or others... at least... Keith s is apparently is no coward... and no mechanic either... Quest
To me it is very obvious that the natural processes could not "create" life... as simple as the atheo-evolution believers would like it to be... Keith S has asked more than once how the designer did it what natural processes could not... and his favorite colleagues too working on solving the mystery of life... How about we try to use their most powerful weapon-science to theorize how the Designer did it... Is anybody willing to propose a theory except Bournagain77? Quest
"...Jack Szostak, a biochemist at Harvard University and one of Joyce’s collaborators, is excited by the findings, particularly because the ribozyme is so much more flexible than earlier versions. But, he said, “I am skeptical that life began in this way.” Szostak argues that this scenario would require both left-handed and right-handed RNA enzymes to have emerged at the same time and in the same place, which would be highly unlikely..." Quest
Here is yet another intelligently designed experimental attempt at proving Intelligent Design is false and blind undirected forces and chemicals is true. http://news.yahoo.com/scientists-create-may-lifes-first-spark-201624804.html . DavidD

OK,... and then what else? Dionisio
The total lack of any kind of experimental evidence leading even to re-creation of life; not to mention spontaneous emergence of life... is the most humiliating embracement to the evolutionists and the whole so-called "scientific establishment" around it... Let's just pretend that the scientists were able to re-create... somehow a prokaryotic cell... How are they going to get to eukaryotic cell since endosymbiosis only exist in science fiction books..? The genes needed for the "evolution" of prokaryotic cells into eukaryotic must have come from space because there is no evidence whatsoever they came from some "simple or simpler" organism on the Earth... So... the summary of it is simple... If scientists ever were able to re-create a simple life form... which they will not, they have huge building blocks to overcome after... However... the first one is impossible to overcome in the first place... Quest
Chirally Sensitive Electron-Induced Molecular Breakup and the Vester-Ulbricht Hypothesis DOI: http://dx.doi.org/10.1103/PhysRevLett.113.118103 We have studied dissociative electron attachment in sub-eV collisions between longitudinally polarized electrons and chiral bromocamphor molecules. For a given target enantiomer, the dissociative Br anion production depends on the helicity of the incident electrons, with an asymmetry that depends on the electron energy and is of order 3×10 ?4 . The existence of chiral sensitivity in a well-defined molecular breakup reaction demonstrates the viability of the Vester-Ulbrict hypothesis, namely, that the longitudinal polarization of cosmic beta radiation was responsible for the origins of biological homochirality. https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.113.118103
Say what? :) Dionisio
Joyce's work reminds me of this cartoon: Atheist's logic 101 "If I can only create life here in the lab (or in my computer), it will prove that no intelligence was necessary to create life in the beginning" http://legacy-cdn-assets.answersingenesis.org/assets/images/articles/ee/v2/life-by-chance.jpg bornagain77
