In living organisms today, complex molecules like RNA and DNA are constructed with the help of enzymes. So how did these molecules form before life (and enzymes) existed? Why did some molecules end up ...

The sugar ribose is more quickly phosphorylated compared to other sugars with the same chemical formula but a different shape. This selective phosphorylation could explain how ribose became the sugar ...
Poly(ADP‐ribose) polymerases (PARPs) are a family of enzymes that play a crucial role in maintaining genomic integrity by detecting DNA damage and facilitating its repair. By catalysing the covalent ...
An artist’s impression of a single strand of ribonucleic acid, or RNA, a molecule thought to be an important precursor for life’s origins on Earth. (Christoph Burgstedt/Getty Images) How life begins ...
Nasa has made a significant breakthrough in understanding how life may have originated on our planet after identifying crucial sugars on an ancient asteroid located 200 million miles from Earth. The ...
An artistic representation of the temperature dependence of the RNA free-energy landscape (FEL) of folding. The authors showed that RNAs undergo a phase transition in the cold and misfold due to the ...
