← Life Sciences & MedicineIf a cell's nuclear receptor lacks its ligand-binding domain, which consequence follows?
A)Increased receptor translocation to cytoplasm
B)Constitutive receptor-DNA binding occurs
C)Receptor dimerization is greatly enhanced
D)Transcription activation remains impaired✓
💡 Explanation
Without a ligand-binding domain, the receptor cannot bind its activating signal, therefore, the receptor's ability to initiate transcription will be compromised, because ligand binding is crucial for receptor activation, rather than impacting its location or binding affinity.
