In a system of purified components , binding of promoter fragment ( TTGTAGTTGGGCACATAGTAGAGCTCACAAAATGTT ) containing a androgen response element 2 from __SP__ __NODE__ gene and a protein fragment containing a DNA binding domain from __SP__ __NODE__ protein is greater than binding of promoter fragment ( TTGTAGTTGGGCACATAGTAGAGCTCA ) containing a androgen response element 2 from __SP__ __NODE__ gene and a protein fragment containing a DNA binding domain from __SP__ __NODE__ protein .
