The left-handed spiral of each Z-DNA strand is highlighted on the left. Binding and bonding of the two zinc finger domains (shown in red) from the CTCF protein to Z-DNA (shown in blue). This protein ...
Under physiological conditions, most double-stranded nucleic acids adopt right-handed helical conformations such as B-DNA or A-RNA. However, under specific cellular stresses, nucleic acids can ...
