Which of the following describes how steroid hormones regulate gene expression?
A) They bind to control elements in a regulatory gene and promote synthesis of that operon.
B) They activate translation of certain mRNAs.
C) They promote the degradation of specific mRNAs.
D) They bind to intracellular receptors and alter transcription of specific genes.

Question

Quizplus · Accepted Answer

Steroid hormones pass through the cell membrane and bind to intracellular receptors. The hormone-receptor complex then moves into the nucleus and binds to specific DNA sequences, altering the transcription of target genes. This process does not involve direct action on mRNAs or operons, nor does it primarily promote mRNA degradation.
