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

(Christoph Burgstedt/iStock/Getty Images Plus) The RNA world hypothesis posits that molecules made up of ribonucleic acids (RNA) are responsible for kickstarting evolution and all life on Earth – and ...

Chemists have demonstrated how RNA (ribonucleic acid) might have replicated itself on early Earth -- a key process in the origin of life. Chemists at UCL and the MRC Laboratory of Molecular Biology ...

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 ...

Although the genetic material of most living organisms is DNA, various self-replicating agents rely instead on RNA, including RNA ...

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

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 ...

The CRISPR-Cas gene-editing system has long been the focus of research as a promising tool in genome editing. However, the emphasis has been on its underlying mechanisms and nucleases. In contrast, ...
