Asteroids – rocky near-Earth objects of the sun – are the parent bodies of most meteorites. And the theory suggests that chemical reactions within asteroids can create some of the essential elements for life.
Researchers found sugars such as arabinose and xylose ̵
Ribose plays an extremely important role in our human biology. It exists in our RNA (ribonucleic acid) molecules and delivers messages from our DNA to help build proteins for our bodies, according to a press release.
"It is remarkable that in such a molecule can be found as fragile as ribose. ancient material, "said NASA's Jason Dworkin, co-author of the study, in a press release.
The discovery of ribose also suggests that RNA evolved before DNA, giving scientists a clearer picture of how life could have been shaped.
DNA has long been regarded as a "template for life" – but RNA molecules have more options, such as replication without the aid of other molecules, according to a press release, these additional capabilities, combined with the fact that researchers have not yet discovered sugars in DNA in meteorites, supports The theory that "RNA coordinated the machine of life before DNA."
