4 days ago · In the anatomy of a gene section, we learned that genes often have regulatory sequences that determine if and when they get expressed. Most such regulatory sequences control gene expression by binding to specific proteins that either enhance or repress transcription. This animation begins in a tissue in which a particular gene product is not ...
