One of the greatest mysteries of our planet is how a soup of lifeless chemicals transformed into the first living cell. There are several competing theories about where this happened, from frozen ...

In most modern cells, DNA stores the genetic blueprint, and relies on proteins to replicate, repair and build from those blueprints. At the same time, proteins require instructions from DNA to be made ...

Explore The RNA World and the 'sweet spot' for life's earliest beginnings on Earth. Discover how RNA catalyzed life and the precise conditions that allowed ...

Despite being made from a relatively simple set of building blocks, ribonucleic acid (RNA) has a broad array of complex responsibilities. From providing structure to carrying the instructions for ...

In the early 1960s, the RNA world hypothesis emerged as an answer to this question. RNA is the single-stranded cousin of DNA, the molecule that contains the genetic information for cellular biology.

New research has pinned down the onset of the "RNA World," a hypothetical time in Earth's very early history when RNA was the ...

Cancer biology—and, in turn, cancer treatment—have come a long way in the last few decades. Most people recognize this ...

RNA is the molecule that reads the genetic information stored in DNA. It's critical for the proper functioning of cells, and in a new study scientists have discovered a way of tagging RNA with a ...

A newly revealed “aging cliff” in sperm RNA marks a conserved molecular transition from youth to later life, offering fresh insight into how a father’s age may influence the earliest stages of ...

More than four billion years ago, Earth was a very different place. Pools of water froze and thawed in cycles, minerals shaped reactions, and molecules bumped into each other by chance. Out of this ...
