Key building blocks of DNA and RNA can be made from the same raw materials. This finding suggests that instead of one or the other kick-starting life on Earth, both chemicals were involved in the ...

RNA World is a fascinating theory but it may not hold true. The problem is that the ingredients, such as enzymes, to make RNA World work just didn't exist on early Earth. For decades, chemists have ...

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.

LIFE ON EARTH may have originated with DNA's cousin RNA, but how the modern world evolved from the RNA world is still mostly unknown. Now, in a new study published last week in the journal Nature, ...

If DNA is a book, then how is it read? Learn more about the DNA transcription process, where DNA is converted to RNA, a more portable set of instructions for the cell. The process of transcription can ...

Take note, DNA and RNA: it’s not all about you. Life on Earth may have begun with a splash of TNA, a different kind of genetic molecule altogether. That is not to say that TNA will dethrone RNA ...

There are a number of theories about how life began on Earth, but one new study published October 3 in ACS Nano suggests that the building blocks of life could have been created with liquid crystals.

April 26 (UPI) --New evidence found in meteorites suggests the ingredients for life came from space. Scientists at NASA and in Japan confirmed Tuesday they found all five key building blocks of DNA ...

Scientists successfully sequence the RNA from woolly mammoths found in Siberia that lived up between 10,000 thousand and ...

More of the ingredients for life have been found in meteorites. Space rocks that fell to Earth within the last century contain the five bases that store information in DNA and RNA, scientists report ...
