A 50 year history of technologies that drove discovery in eukaryotic transcription regulation.

Transcription regulation is critical to organism development and homeostasis. Control of expression of the 20,000 genes in human cells requires many hundreds of proteins acting through sophisticated multistep mechanisms. In this Historical Perspective, I highlight the progress that has been made in elucidating eukaryotic transcriptional mechanisms through an array of disciplines and approaches, and how this concerted effort has been driven by the development of new technologies.
