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, ...

RNA probably came before DNA, serving as the storehouse of genetic information and driving chemical reactions; a ...

In an investigation to find out what sparked life on Earth, researchers have discovered that RNA formed through surprisingly ...

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 ...

A breakthrough experiment, published in the Proceedings of the National Academy of Sciences, offers compelling support for ...

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 ...

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.

This seminar explores the link between modern RNA and suggestions for a prebiotic RNA world that existed some 3.8 billion years ago. Topics include prebiotic synthesis, replication and in vitro ...

The relationship between RNA sequences and their resultant structures is central to understanding evolutionary processes and molecular robustness. Genotype–phenotype mapping studies reveal how subtle ...

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.] ...

Researchers from Tokyo University of Science have engineered a ribozyme structure which mimics the early RNA world and provides novel insights on the role of RNA in primitive life, to its various real ...
