B-Z junction in DNA,molecular model. Deoxyribonucleic acid (DNA) occurs in three forms,A-DNA,B-DNA and Z-DNA. The first two are right-handed,with B-DNA being the more common form. Z-DNA is left-handed,and a higher energy form of the DNA double helix. It forms from the lower energy states,and then relaxes back to B-DNA. During the transformation stages,junctions occur between the two forms,as shown here | |
