Brought life to earth asteroids meteors on NASA's research found evidence to support the theory of

ANKARA - The American Aviation and Space Agency (NASA) made ​​a new study on carbon meteorites, their DNA could be brought to Earth for some of the necessary building blocks emerged.

Research published in the journal, the American National Academy of Sciences, has been long debated some of the materials required for the formation of the first forms of life on Earth göktaşlarıyla theory that the way to a new and strong support provided.

Research scientists, contributing to the construction of DNA and RNA nucleic acid that form the basis of organic carbon-rich chondrite-called 11 göktaşını spectrometer scanned devices. The researchers, 3 purines (uric acid, purine corpuscles, especially the main element of the complex structure of nitrogenous compound) found the basis of nucleic acid.

This material is commonly found in carbonaceous chondrite, the world's biological structure, which indicates that there very rarely or not at all scientists, also in the vicinity of those meteors falling soil and ice samples in the mixture and no trace of the three underlined rastlamadıklarının.

Geophysical Laboratory of the Carnegie Institute of Washington, participated in the research, Jim Cleaves of the Earth is not the biochemistry of nucleic acid base components in a significant way to detect them, supports the theory that they might be extraterrestrial sources said. The American scientist, it provides the basic building blocks for life on Earth meteors molecules had demonstrated that the material might have underlined the kit. (Mm)
