BUFFALO, N.Y. — The RNA world theory suggests that life on Earth began with RNA molecules that copied themselves. It’s believed this self-replication eventually gave rise over millions of years to DNA ...

The origin of life continues to remain a matter of debate. The ribonucleic acid (RNA) world hypothesis proposes that 'ribozymes' which store genetic information and possess catalytic functions may ...
How was complex life able to develop on the inhospitable early Earth? At the beginning there must have been ribonucleic acid (RNA) to carry the first genetic information. To build up complexity in ...

In a new book, astrophysicist Mario Livio describes how the existence of life on Earth can be traced back to an RNA-based “protocell.” The following is an excerpt from Is Earth Exceptional?: The Quest ...

Atomic-resolution structure of a ribozyme yields insights into RNA catalysis and the origins of life
Santa Cruz, CA — Which came first, nucleic acids or proteins? This question is molecular biology’s version of the “chicken-or-the-egg” riddle. Genes made of nucleic acids (DNA or RNA) contain the ...
A forested hill and clouds are in the background of an image of a shallow pool of steaming water, with the ground underneath colored in shades of beige, red, and brown. Life may have first emerged in ...
