A 45-nucleotide strand of RNA can now synthesize both its mirror-image complement and a copy of itself, bringing scientists closer than ever to demonstrating how life could have emerged from chemistry ...
Two separate laboratory breakthroughs have produced RNA molecules that can build copies of themselves or assemble functional structures without any help from proteins or DNA. These results offer the ...
In Biology 101, we learn that RNA is a single, ribbon-like strand of base pairs that is copied from our DNA and then read like a recipe to build a protein. But there's more to the story. Some 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 ...
A new study shows that the RNA demethylase FTO stabilizes EGR1 mRNA through m6A modification, activating a STING1-driven ...
Atlanta—ACS Spring 2026, a meeting of the American Chemical Society, began with a flurry of talks early Sunday morning. During a session hosted by the Division of Biochemistry and Chemical Biology ...
The ATR–ATRIP kinase complex safeguards genome integrity by coordinating cellular responses to DNA damage and replication stress. Two recent cryo-EM studies resolve the structural basis of ATR–ATRIP ...
Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such structure, the G-quadruplex (G4), looks like a knot. These knots can play ...
