our results led to the conclusion that androgen receptor , ( ra ) , takes up preferred but different conformations when bound to testosterone ( t ) and to 17 beta-hydroxy-5 alpha-androstan-3-one ( 5 alpha-dihydrotestosterone , dht ) , respectively , and that the resulting steroid-receptor complexes bind preferentially to different chromatin acceptor sites .
