In cell extract from liver of adult __SP__ , binding of a mutant DNA fragment ( C 113A A 112C T 108A T 107A T 105C ) containing a __NODE__ response element from __SP__ __NODE__ gene and __SP__ __NODE__ protein is the same as binding of a mutant DNA fragment ( A 114G C 113T A 112C C 109T T 108A T 107A A 106T T 105C ) containing a __NODE__ response element from __SP__ __NODE__ gene and __SP__ __NODE__ protein .
