In Eukaryotic Cells, Glucocorticoids Regulate Gene Expression by

In eukaryotic cells, glucocorticoids regulate gene expression by

A) binding to and activating a previously synthesized but inactive enzyme.
B) binding first to a specific steroid receptor which then binds to an inactive enzyme and causes activation.
C) binding to the sigma subunit of RNA polymerase and stimulating transcription.
D) binding first to a specific steroid receptor which then binds to a specific hormonal control site on the DNA and activates transcription.
E) binding first to a specific steroid receptor which then binds to the nuclear matrix and blocks mRNA degradation.
