Transmission photography of single-strand (a), (c) and double-strand (b), (d) 2D sinusoidal waves (a), (b) and 3D DNA helices (c), (d) using . Each helix is made of a backbone of
N = 70 particles with a pitch of and a diameter of . There are 10 particles per pitch. The two helices in the double-strand structure are offset by 3/8 pitch. The particle size in the insets is set as to enhance visibility. |
