Ribonucleic acid, also called RNA, is a molecule present in all living cells. It plays a critical role in transmitting genetic instructions from DNA and creating proteins. With the power to execute a ...

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 ...

SgrS is a 227-nt small RNA that is expressed in Escherichia coli during glucose-phosphate stress, a condition associated with intracellular accumulation of glucose-6-phosphate caused by disruption of ...

This study sheds light on the molecular function of one of the enzymes with RNA helicase activity involved in the synthesis process of the large ribosome subunit. By combining biochemical, genetic and ...
