Inside every cell, thousands of molecular signals collide, overlap, and compensate, obscuring the true drivers of gene expression.

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 ...

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 ...

Bacteria need to constantly adapt to compete against other species for nutrient sources and to survive against threats such as antibiotics and toxins. In an effort to understand how bacteria control ...

Transcription is the process of copying DNA to RNA. The accuracy of transcription processes varies widely among species, across cell types and within distinct regions of the genome, with profound ...
