Living cells are fundamentally nonequilibrium systems, meaning they constantly spend energy through seemingly one-way, ...

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 ...

Much of the phenotypic variation that is observed within and between species is the result of differences in gene regulation: specifically when, where and how much the genes are expressed. Given the ...

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, ...

This breakthrough allows researchers to visualize where individual genes are active at the cellular level—information that has long been missing due to technical limitations in tea biology. By ...

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 ...

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 ...

CRISPR-Cas9 has been widely adapted for use in transcriptional modulation and epigenetic engineering with deactivated Cas9 (dCas9) systems to enable CRISPR interference (CRISPRi) and CRISPR activation ...

When a gene is active, there is cellular machinery that transcribes the sequence of that gene from DNA into messenger RNA. This is a fundamental cellular process that is essential to the proper ...

Scientists at IOCB Prague are uncovering new details of gene transcription. They have identified a previously unknown molecular mechanism by which the transcription of genetic information from ...
