Building blocks of DNA and RNA could have appeared together before life began on Earth![]() La Jolla CA (SPX) Apr 03, 2019 Scientists for the first time have found strong evidence that RNA and DNA could have arisen from the same set of precursor molecules even before life evolved on Earth about four billion years ago. The discovery, published April 1 in Nature Chemistry, suggests that the first living things on Earth may have used both RNA and DNA, as all cell-based life forms do now. In contrast, the prevailing scientific view - the "RNA World" hypothesis - is that early life forms were based purely on RNA, and only ... read more |
