Humans have it. So does Drosophila. But not yeast. That "it" is a small pause at the start of gene activity—a brief molecular ...

A newly discovered promoter element "start" points to a shared regulatory syntax for controlling transcription initiation in ...

In eukaryotes, the tight or loose packaging of the genes in chromatin (DNA plus specific proteins) can control whether the genes can be expressed to form their encoded product. Chromatin is usually ...

Researchers turned programmable proteins into a novel genetic tool, potentially enabling tighter control of gene expression. LacI is a tetrameric protein, using two dimers to bind two specific, ...
