Scientists may have a step forward in understanding how life on our planet came to exist. The mystery of how tiny molecules of RNA came to be enclosed within membranes, forming the very first cells, ...

A study identifies a novel self-replicating circular RNA in hot springs, revealing unexpected diversity of RNA replicators, ...

The beginning of life on Earth and its evolution over billions of years continue to intrigue researchers worldwide. The central dogma or the directional flow of genetic information from a deoxyribose ...

LA JOLLA (March 4, 2024)—Charles Darwin described evolution as "descent with modification." Genetic information in the form of DNA sequences is copied and passed down from one generation to the next.

DNA is the backbone of the genetic code so, logically, decoding and understanding the genetic sequence along with epigenetic modifications came first. Yet, RNA and the emerging field of ...

Prospects for understanding the origin of the RNA world / Gerald F. Joyce and Leslie E. Orgel -- Reading the palimpsest: contemporary biochemical data and the RNA world / Steven A. Benner ... [et al.] ...

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 ...

Two University of Chicago scholars have been elected to the National Academy of Sciences, joining other scientists and researchers chosen in “recognition of their distinguished and continuing ...

Researchers updated the global catalogue of human-infective RNA viruses to 239 ICTV-recognised species, incorporating ...

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 ...
