What made ribose the sugar of choice for life's code? Scientists at Scripps Research may have cracked a major part of this mystery. Their experiments show that ribose binds more readily and ...
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 ...
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 ...

A giant impact on the early Earth could have brought the building blocks of RNA to our planet, which new research suggests ...
How life begins remains an unsolved question. One key component might be RNA, a molecular cousin of DNA found in every form of life on Earth, and now scientists say they have shown how it could have ...
In a recent study published in Nature Metabolism, researchers attempted to identify new genes and molecular pathways that might supply energy when the availability of glucose or other nutrients is ...
