Quizplus · Accepted Answer

Hormone-induced gene expression is mediated by specific sequences in the DNA known as hormone response elements (HREs). These HREs are binding sites for hormone receptors, and when a hormone binds to its receptor, it triggers a cascade of events that result in the activation of gene expression. HREs are typically located upstream of the gene they regulate and can be either enhancers or silencers of transcription.
