New research suggests that the sugar ribose -- the “R” in RNA -- is probably found in comets and asteroids that zip through the solar system and may be more abundant throughout the universe than was ...

Scientists analyzing asteroid Bennu samples have discovered sugars essential to life and a unique gum-like substance, offering new insights into early solar system chemistry and the origins of life.

Poly(ADP-ribosyl)ation by poly(ADP-ribose) polymerases regulates the interaction of many DNA damage and repair factors with sites of DNA strand lesions. The interaction of these factors with poly (ADP ...

Researchers at Gifu University’s Institute for Glyco-core Research have developed two synthetic approaches to produce a fragment of a molecule called poly(ADP-ribose). By developing two ways to ...

The discovery of ribose sugar in ancient meteorites just made space rocks a little sweeter. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. A new ...

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 intriguing findings bolster the theory that asteroids seeded the early Earth with life's chemical components - a process ...

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 ...

Many proteins that respond to DNA damage are recruited to DNA lesions. We used a proteomics approach that coupled isotopic labeling with chromatin fractionation and mass spectrometry to uncover ...

Space rocks that fell to Earth contain ribose, an essential molecule for life’s genetic machinery, and other related sugars. The finding, reported online November 18 in Proceedings of the National ...
