Question

13 multiple choice 10 points which of the following diagrams best represents hormone - activated gene expression?

Explanation:

Steroid hormones are lipid - soluble and can pass through the cell membrane. They bind to receptor molecules inside the cell (intracellular receptors). The hormone - receptor complex then enters the nucleus and binds to specific DNA sequences, regulating gene expression (transcription). The first diagram shows a steroid hormone binding to a receptor molecule, forming a hormone - receptor complex that acts on transcription, which is consistent with hormone - activated gene expression. The other diagrams have incorrect components (e.g., peptidoglycan is related to bacterial cell walls, not hormone - gene expression; cholesterol in the context of exocytosis is not relevant to hormone - activated gene expression; induction and translocation in the third diagram and apoptosis and transduction in the fourth diagram do not represent the typical steroid - hormone - activated gene - expression pathway).

Answer:

The first diagram (with Steroid Hormone, Receptor Molecule, Hormone - Receptor Complex, Transcription).
