In Eukaryotic Cells, Adrenal Corticosteroids Regulate Gene Expression by Binding

In eukaryotic cells, adrenal corticosteroids regulate gene expression by binding to

A) allosteric effector sites on an inactive enzyme.
B) a receptor that, in turn, interacts with DNA and activates transcription.
C) a receptor that, in turn, migrates to the nuclear matrix and blocks RNA degradation.
D) ribosomes and stimulating translation.
