Unusual Z-form deoxiribonucleic acid (zDNA) consists of two anti-parallel strands of nucleotides that form a left-handed double helix; standard B-form DNA forms a right-handed double helix
Standard B-form DNA consists of two anti-parallel strands of nucleotides that form a right-handed double helix, while unusual Z-form DNA forms a right-handed double helix
Shown on the left is standard B-form DNA, which consists of two anti-parallel strands of nucleotides that form a right-handed double helix. Shown on the right is single-stranded section of DNA.
Healthy double-stranded DNA is relatively straight and consistent, while DNA segments with errors or mismatches tend to have kinks or bends, making them irregular and inconsistent.
This section of standard double-stranded DNA is shown in three display formats, including SA surface, spacefill and ball-and-stick formats .
Using specific sequences of DNA that form standard Watson-Crick base pairs, complex DNA lattices can be constructed.

This unusual di-nucleotide contains a looped backbone with two phosphodiester bonds connecting the two nucleotides.
Adenosine Triphosphate (ATP) is composed of a standard adenosine nucleotide with a total of three inorganic phosphate groups.
Adenosine Triphosphate (ATP) is composed of a standard adenosine nucleotide with a total of three inorganic phosphate groups. In this model, two of the phosphate groups can be detached to represent the various forms of AMP, ADP and ATP.
