Question

Which of the following is a region in DNA that binds to a steroid receptor?
A) GRE
B) IRE
C) CRE
D) CREB

Accepted Answer

GRE (Glucocorticoid Response Element) is the region in DNA that specifically binds to glucocorticoid receptors or steroid receptors. The binding of steroid hormones to their receptors at GRE region activates or represses the transcription of target genes. IRE (Iron-Response Element) is a region in RNA that binds to iron regulatory protein, while CRE (Cyclic AMP Response Element) and CREB (Cyclic AMP Response Element Binding protein) are regions that bind to cAMP-response elements, which are involved in various cellular processes such as cell differentiation, proliferation, and apoptosis.
