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 ...

Since the discovery of the double-helical structure of DNA and postulation of the central dogma of molecular biology, stating that the flow of genetic information goes from DNA to RNA to protein, the ...

This image illustrates the chemical structure of a purine molecule, highlighting the numbering of the carbon and nitrogen atoms. The purine structure consists of a pyrimidine ring (positions 1 to 6) ...

Scientists at IOCB Prague are uncovering new details of gene transcription. They have identified a previously unknown ...

Inside every cell, a finely tuned metabolic network determines when to build, recycle, or stop producing essential molecules. A central part of this network is folate metabolism, a process that ...

RNA is one of the bodies most vital molecules, and it comes in a few forms. For example, messenger RNA fills an essential role in gene expression by copying the sequences of active genes, which are ...

DNA and RNA methylation, initially thought to operate as distinct pathways, have been shown to interact closely, shifting our understanding of gene regulation. A team of researchers from the ...

Thomas Gingeras did not intend to upend basic ideas about how the human body works. In 2012 the geneticist, now at Cold Spring Harbor Laboratory in New York State, was one of a few hundred colleagues ...
