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, ...
Every living cell transcribes DNA into RNA. This process begins when an enzyme called RNA polymerase (RNAP) clamps onto DNA. Within a few hundred milliseconds, the DNA double helix unwinds to form a ...
To support drug discovery, a new study has revealed fundamental features of the transcription cycle in the bacteria that causes tuberculosis.
When the molecular machinery in our cells gets to work transcribing the genetic information encoded in DNA into messenger RNA (mRNA), it pauses shortly after starting. Known as promoter-proximal ...
According to this model, sigma (σ) factors bind to RNA polymerase to initiate transcription—the process by which genetic information is copied from DNA to RNA—and then detach after initiation to allow ...
Cardiovascular disease remains the leading cause of mortality worldwide, necessitating deeper insights into its molecular underpinnings beyond genetic predisposition. Epigenetic modifications, ...
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 ...
A proposed function of TADs is to contribute to gene regulation by promoting chromatin interactions within a TAD and by suppressing interactions between TADs. Here, we directly probe the ...
Researchers identified how the poxvirus protein VITF-3 forms a molecular ring that clamps onto DNA with viral RNA polymerase, bending it by 90 degrees to initiate gene copying.
