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

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 ...

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

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.

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 ...

A giant impact on the early Earth could have brought the building blocks of RNA to our planet, which new research suggests ...

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 ...

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 ...

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 ...

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 ...
