Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a particular cell determine what that cell can do. Moreover, each step in the flow of ...

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

To help achieve more precise control of gene therapy, engineers have designed a new control circuit that can keep gene expression levels within a target range. The method could be used to deliver ...

Humans have it. So does Drosophila. But not yeast. That "it" is a small pause at the start of gene activity—a brief molecular halt that may have helped life evolve from simple cells to complex animals ...
