A research team has uncovered a previously unknown type of immune signaling molecule—a novel compound combining histidine and ADP-ribose—produced by bacteria's Thoeris II defense system in ...

How, then, did the molecular building blocks of life first form? Among chemists, it's widely thought that one of these building blocks—a sugar known as ribose, which forms the backbone of RNA ...

It is probably impossible to build this structure with a ribose sugar in place of the deoxyribose, as the extra oxygen atom would make too close a van der Waals contact. The previously published X ...

D-Ribose is a sugar molecule that is naturally found in the body and is essential for producing ATP, which is the main source of energy for the cells. It is commonly used by athletes and people ...

As its name suggests, ribose has more oxygen atoms than deoxyribose. Thus, the elongation period of transcription creates a new mRNA molecule from a single template strand of DNA. As the mRNA ...

It is a polymeric molecule composed of nucleotides, each containing a ribose sugar, a phosphate group, and one of four nitrogenous bases: adenine (A), uracil (U), guanine (G), or cytosine (C). RNA is ...

Get Instant Summarized Text (Gist) A novel immune signaling molecule, histidine-ADP-ribose (His-ADPR), has been identified in bacteria's Thoeris II defense system, expanding known immune signaling ...
