Hormone-Induced Gene Expression is Mediated by Specific Sequences in the DNA

Question

Hormone-induced gene expression is mediated by specific sequences in the DNA known as

A) HREs.
B) HSPs,
C) ESTs
D) STRs..
E) PCRs

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.
