Perhaps inosine was one of the components of the first life forms on Earth

An article published in the journal “Proceedings of the National Academy of Sciences” describes a study on the possible precursors of RNA. A team of Harvard University biologists led by Nobel Prize laureate Jack Szostak is trying to reconstruct the various steps that led to the birth of life with lab experiments and an interesting result came from the use of inosine as a surrogate for guanine, one of the RNA and also DNA bases.
