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 ...

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 ...

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 ...

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

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.

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 ...

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 ...

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 ...

Samples taken from the near-Earth asteroid 162173 Ryugu continue to provide scientists with important insights, this time about the potential beginnings of life on our planet. Hayabusa2 delivered its ...

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.] ...
