In addition , the DNA - binding experiments show that either one of the two MADS domains of a dimer can be sufficient to confer a particular DNA - binding specificity to the complex and that sequences outside the amino - terminal basic region of the MADS domain can , in some cases , contribute to the DNA - binding specificity of the proteins .
