Inosine could be a potential route to the first RNA, Harvard study says
In a paper published in PNAS, Jack W. Szostak, professor of chemistry and chemical biology at Harvard, along with graduate student Seohyun (Chris) Kim, suggest that RNA could have started with a different set of nucleotide bases. In place of guanine, RNA could have relied on a surrogate, inosine.
