Interacting selectively and non-covalently with DNA containing four-way junctions, also known as Holliday junctions, a structure where two DNA double strands are held together by reciprocal exchange of two of the four strands, one strand each from the two original helices. Interacting selectively and non-covalently with DNA containing the open form of a four-way junction, also known as a Holliday junction, a structure where two DNA double strands are held together by reciprocal exchange of two of the four strands, one strand each from the two original helices. The open form of a four-way junction can be diagrammed without any of the strands crossing over. Interacting selectively and non-covalently with DNA containing the crossed form of a four-way junction, also known as a Holliday junction, a structure where two DNA double strands are held together by reciprocal exchange of two of the four strands, one strand each from the two original helices. The crossed form of a four-way junction cannot be diagrammed without any of the strands crossing over, and instead contains a single crossover between two of the strands. Interacting selectively and non-covalently with DNA of a specific structure or configuration e.g. triplex DNA binding or bent DNA binding. Interacting selectively and non-covalently with DNA containing secondary structure elements such as four-way junctions, bubbles, loops, Y-form DNA, or double-strand/single-strand junctions.
