New research shows RNA is preserved for longer than scientists had realized. This is the oldest RNA ever profiled.

Researchers at Stockholm University carefully ground up bits of muscle and other tissue from Yuka and nine other woolly ...

NIMS, in collaboration with Nagoya University, Gifu University, and the University of Adelaide, has developed a method for simultaneously imaging DNA and RNA inside cells using harmless infrared to ...

Chemical structure of guanine, showing its double-ring purine structure and the functional groups involved in hydrogen bonding with cytosine. (Image: Public Domain) Guanine has the chemical formula ...

Scientists have extracted the oldest RNA molecules out of a woolly mammoth, gaining a snapshot into the processes at work in ...

This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

RNAs play an integral part in all kingdoms of life and mediate critical processes from gene regulation to genomic maintenance and protein synthesis. RNAs also have an amazing diversity in structure ...

Inside every cell, a finely tuned metabolic network determines when to build, recycle, or stop producing essential molecules.

Many viruses have genomes made of RNA. In human cells, messenger RNA (mRNA) molecules act as intermediates; cellular machinery copies a DNA sequence into mRNA so that it can then be translated into a ...
