The enzyme tRNA-guanine transglycosylase (TGT) chemically modifies transfer RNA (tRNA) and plays a key role in how ...

tRNAs have a distinct cloverleaf secondary structure and an L-shaped tertiary structure. The cloverleaf structure is formed by the folding of the single-stranded tRNA molecule, which is typically ...

RNA molecules are an integral part of the human body: In cells, they ensure the transfer of genetic information and regulate the activity of genes. Some even act as catalysts, allowing chemical ...

Researchers have now uncovered the 3D structure of the RNA enzyme SAMURI. Their study provides insights into the development of ribozymes and the evolution of catalytically active RNA. Researchers led ...

In the microscopic world of bacteria, gene transfer is a powerful mechanism that can alter cellular function, drive antibiotic resistance and even shape entire ecosystems. Now an interdisciplinary ...

Inosine is a nucleoside that occurs naturally in transfer RNAs (tRNAs) and is essential for proper RNA translation. It is commonly found at the wobble position of anticodons, allowing for greater ...

The Human Genome Project (HGP) ultimately revealed a DNA sequence of 3 billion base pairs known as the human genome, 1 spurring an enormous technological advance in scientific research and the ...
