Solution:

Z-DNA is a rare form of DNA which was reported by Rich. Its helical coiling is left to right, so it is left-handed DNA or clockwise DNA.
Helix pitch = 45 Å
Number of base pairs per turn = 12 pairs.
Distance between two neighbouring base pairs = 3.7 Å.
Diameter = 20 Å.
Z-DNA is also known as Zig-Zag DNA.
