A newly identified class of RNA molecules has been discovered in bacteria living inside the human body. These circular ...

Researchers from the Icahn School of Medicine at Mount Sinai have shed valuable light on the nuanced functions and intricate regulatory methods of RNA editing, a critical mechanism underlying brain ...

Ribosomes are composed of two subunits, the small and large subunits, each containing specific rRNA molecules. The main types of rRNA include: Small Subunit rRNA: In prokaryotes, the small subunit ...

Researchers identify a shared RNA-protein interaction that could lead to broad-spectrum antiviral treatments for ...

The natural RNAi mechanism can be directed by either short interfering RNA (siRNA) or microRNA (miRNA). 1 There are four key steps in the RNAi pathway. When miRNA acts as the guide for RNAi, only a ...

RNA in cells performs an astounding number of functions. Messenger RNA carries the sequences of active genes to cellular machinery that turns it into proteins. And transfer RNA molecules are an ...

CRISPR-Cas systems are adaptive immune systems found in prokaryotes that defend against invading nucleic acids through CRISPR RNA-guided cleavage. Type V CRISPR-Cas (Cas12) systems, in particular, ...

All starting from the same DNA, neurons ultimately take on individual characteristics in the brain and body. Differences in which genes they ...

Nucleic acids are complex biological molecules that store and transmit genetic information in all living organisms. They are essential for the survival and reproduction of life on Earth. The two main ...

Stanford Medicine researchers have developed a blood test capable of detecting cancers, the ways cancer resists treatments and tissue injury caused by non-cancerous conditions. The new test analyzes ...
