    • It may be noted that adenine has structurally different conformations arising due to the rotation of furanose ring in the nucleic acids. The two basic forms C 3′ -endo (a=5.9) and C 2′ -endo (a=7.0) of furanose ring characterize two distinctly different families of nucleic acid structures. The reorientation of bases at high force may lead to a conformational transition in the deoxyribofuranose rings from C 3′ -endo pucker to C 2′ -endo pucker in a steplike jump which may give about 18% extension in interphosphate distance.
