One of the first-ever images of the open complex that forms when RNAP encounters DNA and kicks off the process of transcription. Every living cell transcribes DNA into RNA. This process begins when an ...

Molecular biologists have long believed that the beginning of a gene launched the process of transcription—the process by which a segment of DNA is copied into RNA and then RNA helps make the proteins ...

Inside every cell, thousands of molecular signals collide, overlap, and compensate, obscuring the true drivers of gene expression. Scientists have now developed a way to silence that cellular noise, ...

Aging, neurological diseases and our bodies' stress response are all linked to the tiny power plants inside each cell known as mitochondria. To function properly, mitochondria must first read ...
