Most DNA is right-handed B DNA, turning every 3.4 nm with 10 bases per span, while left-handed Z DNA turns every 4.6 nm with 12 bases per span.
B DNA is the common right-handed helix, turning every 3.4 nm with 10 bases per turn, while Z DNA is a left-handed helix turning every 4.6 nm with 12 bases per turn.
| Text | Most DNA is a right handed helix called B DNA, and makes a turn every 3.4 nm and has 10 bases within that span DNA can also be left handed which is called Z DNA, and makes a turn every 4.6 nm and has 12 bases within that span |
