researchers found in a meteorite of Martian origin of many of boron salts, which have played a major role in the formation of RNA, an important connection to the origin of life.
This meteorite was found in Antarctica during an expedition of 2009-2010, and studied it for James Stevenson of the NASA Astrobiology Institute at the University of Hawaii at Manoa. The researchers analyzed the veins of clay in the meteorite by ion microprobe. It was found that boron therein is 160 ppm, the number is 8 times more than in other meteorites.
boron salts played an important role in the origin of life on Earth, because they stabilize ribose, a component of RNA. RNA was a carrier of information, before there was DNA, the scientist said.
Before RNA molecule is a DNA genetic information transmitted in the first living cells. RNA appeared in the chemical evolution of inanimate nature. The most difficult stage of the process – a formation and stabilization of the ribose. Practical tests have shown that ribose could not be without boron salts.
