This image illustrates the process of gene transcription within a cell. The DNA double helix unwinds to expose a specific sequence, allowing RNA polymerase to synthesize a complementary pre-mRNA ...

Every cell in our body contains the same DNA, yet liver cells are different from brain cells, and skin cells differ from muscle cells. What determines these differences? It all comes down to gene ...

'Random DNA' is naturally active in the one-celled fungi yeast, while such DNA is turned off as its natural state in mammalian cells, despite their having a common ancestor a billion years ago and the ...

RNA Polymerase (shown in blue) moves across a template strand of DNA (shown in purple) and transcribes it into RNA (shown in red). But DNA damage blocks the RNA polymerase, causing it to stall and ...

Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and ...

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 ...

To support drug discovery, a new study has revealed fundamental features of the transcription cycle in the bacteria that causes tuberculosis.

Scientists at the Massachusetts Institute of Technology (MIT) have invented a new single-cell nascent RNA sequencing technique that lets them observe the timing of gene and enhancer activation in ...

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, ...

Recent studies reveal that changes in gene regulation, not just gene sequences, are crucial for the evolution of animal ...
