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 ...
Atomic-resolution structure of a ribozyme yields insights into RNA catalysis and the origins of life
Santa Cruz, CA — Which came first, nucleic acids or proteins? This question is molecular biology’s version of the “chicken-or-the-egg” riddle. Genes made of nucleic acids (DNA or RNA) contain the ...
Researchers from A*STAR’s Genome Institute of Singapore (GIS) have found an innovative approach to sequencing single-cell ribonucleic acid (RNA) to study the roles of RNA structure in individual cells ...
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 ...
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 ...
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 ...
When the gene is transcribed into RNA, the chain of repeats forms a hairpin loop —a tangled structure that functions like a sticky trap for essential proteins. These proteins, which play a vital role ...
RIKEN researchers have discovered how an enzyme modifies gene expression by targeting certain stretches of messenger RNA ...
