The chemical structure of uracil, showing its single-ring pyrimidine structure. Uracil forms hydrogen bonds with adenine in RNA, contributing to the molecule's structure and function. (Image: Public ...

Genetic editing holds promise to treat incurable diseases, but the most popular method — CRISPR — sometimes does more harm than good. A new study from University of California San Diego and Yale ...

The origins of life remain a major mystery. How were complex molecules able to form and remain intact for prolonged periods without disintegrating? A team has demonstrated a mechanism that could have ...

RNA could be considered DNA’s younger sibling. From the very beginning, RNA’s milestones came later and attracted less attention than DNA’s milestones. For example, the discovery of DNA’s structure ...

While the central dogma of molecular biology outlines the linear flow of genetic information from DNA to RNA to proteins (black lines), glycomics introduces a “3rd code of life”—glycans—that operates ...

New research shows how RNA, a key molecule for life, may have formed on early Earth using simple chemistry and materials delivered by asteroid impacts, linking space science with the origins of life ...
