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

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 ...

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, ...

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 ...

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 ...

A research team at Florida State University's Institute of Molecular Biophysics and Department of Chemistry and Biochemistry ...

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

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 ...

Researchers at the Federal University of São Paulo (UNIFESP) in Brazil have discovered that SARS-CoV-2, the virus that causes ...
