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 ...

Recent research showed that an artificially constructed RNA self-replicating system modeling primitive life at the origin of life evolved to become more prone to extinction under certain experimental ...

While evolution is often considered from a DNA- and protein-centric view, RNA-based regulation can also impact gene expression and protein sequences. Here we examine interspecies differences in ...

Recent research showed that an artificially constructed self-replicating RNA system modeling primitive life at the origin of ...

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 ...

Researchers at University of Tsukuba have discovered a previously unknown self-replicating circular RNA in a high-temperature hot spring environment. Previously, self-replicating RNAs identified 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.] ...

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 ...
