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 ...

Ask a friend what DNA is and, chances are, they have a general idea. Seventy years after scientists discovered the two-stranded helix, DNA (deoxyribonucleic acid) is widely understood as the keeper of ...

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 ...

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 ...

Strange “chimeric” RNA once thought to be the product of cancer is actually an important controller of women’s health, including influencing their susceptibility to infectious disease and autoimmune ...

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 published in Nature Communications, University of California ...

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 ...

The RNA world hypothesis posits that molecules made up of ribonucleic acids (RNA) are responsible for kickstarting evolution and all life on Earth – and scientists just discovered a crucial new piece ...
