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 ...

Life’s instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing RNA in eukaryotic cells and eventually giving rise to proteins. Scientists ...

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, ...

With a new study in the journal Cell, researchers at Stanford University and Stockholm University have contributed to increased knowledge about gene regulation in human cells. How genes are turned on ...

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 ...

Precise control of gene expression—ensuring that cells make the correct components in the right amount and at the right time—is vital for all organisms to function properly. Cells must regulate how ...

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 ...

Tampa (BLOOM) – Understanding the intricate process of aging has been a subject of fascination for scientists and researchers. While aging is a natural part of life, recent studies have shed light on ...

This Brush Up is sponsored by Cayman Chemical. Learn more about chemical inhibitors of histone modification. Histone modification affects how tightly DNA wraps around histone proteins, yielding ...
