In most modern cells, DNA stores the genetic blueprint, and relies on proteins to replicate, repair and build from those ...

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 ...

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 ...

Researchers have catalogued thousands of sites in the brain where RNA is modified throughout the human lifespan in a process known as adenosine-to-inosine (A-to-I) editing, offering important new ...

Researchers at the International Institute of Molecular and Cell Biology in Warsaw (IIMCB), led by Prof. Gracjan Michlewski, have shown that a subtle difference at the very beginning of an RNA ...

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 ...

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 ...

A little-known RNA molecule found only in women may influence immunity, infection severity, and autoimmune risk.
