Z-DNA can form ''invitro'' from B-DNA by raising negative super helical stress or under low salt conditions when deoxycytosine is 5-methylated. The formation of Z-DNA ''invivo'' is an energy requiring process. Z-DNA forms behind a moving RNA polymerase when it moves through DNA double helix during transcription and is subsequently stabilized due to the generation of negative supercoils. | Z-DNA can form ''invitro'' from B-DNA by raising negative super helical stress or under low salt conditions when deoxycytosine is 5-methylated.

Z-DNA forms behind a moving RNA polymerase when it moves through DNA double helix during transcription and is subsequently stabilized due to the generation of negative supercoils. Z-DNA is the first single crystal X-ray structure of a DNA fragment. It was crystallized as a self complementary DNA hexamer d(CG)<sub>3</sub> by Andrew Wang, Alexander Rich and their co-workers at MIT in 1979. <ref name = 'Rich'>PMID:12838348</ref><ref name ='Wang'>PMID:17485386</ref> | ||
