NASA Ames Reproduces the Building Blocks of Life In Laboratory

hypnosec writes "Scientists at NASA's Ames Research Center have reproduced non-biologically the three basic components of life found in both DNA and RNA — uracil, cytosine, and thymine. For their experiment scientists deposited an ice sample containing pyrimidine — a ring-shaped molecule made up of carbon and nitrogen — on a cold substrate in a chamber with space-like conditions such as very high vacuum, extremely low temperatures, and irradiated the sample with high-energy ultraviolet photons from a hydrogen lamp. Researchers discovered that such an arrangement produces these essential ingredients of life. "We have demonstrated for the first time that we can make uracil, cytosine, and thymine, all three components of RNA and DNA, non-biologically in a laboratory under conditions found in space," said Michel Nuevo, research scientist at NASA's Ames Research Center, Moffett Field, California. "We are showing that these laboratory processes, which simulate conditions in outer space, can make several fundamental building blocks used by living organisms on Earth."

Uracil and thymine not found in both DNA and RNA.

... the three basic components of life found in both DNA and RNA -- uracil, cytosine, and thymine.

The three components present in both DNA and RNA are cytosine, guanine and adenine. Uracil is only present in RNA, and thymine only in DNA.

Re: And still

You couldn't be more wrong about that. While it is true that said data (that there is none available) shouldn't be weighed very strongly, it is data. In other news, if you choose not to decide you still have made a choice.
