DNA is usually found in the B form under physiological conditions. The B-form conformation is stabilized by water molecules bound to the minor groove. You can see them as red dots <scene name='72/725442/Water_spine/1'>in this view</scene>. Sometimes kinks are found in the B helix at transcriptional control regions. These kinks can either be intrinsic to the DNA sequence or caused by transcription factor binding. | DNA is usually found in the B form under physiological conditions.
