Zooming in on DNA Structure - Visible Body
WEBDNA is a macromolecule consisting of two strands that twist around a common axis in a shape called a double helix. The double helix looks like a twisted ladder—the rungs of the ladder are composed of pairs of nitrogenous bases (base pairs), and the sides of the ladder are made up of alternating sugar molecules and phosphate groups.
Molecular models of DNA - Wikipedia
WEBDNA molecular dynamics modeling involves simulating deoxyribonucleic acid (DNA) molecular geometry and topology changes with time as a result of both intra- and inter- molecular interactions of DNA.

Watson and Crick: 3-D structure of DNA :: DNA from the Beginning
WEBWatson and Crick: 3-D structure of DNA :: DNA from the Beginning. The DNA molecule is shaped like a twisted ladder. While visiting Cambridge in 1952, Erwin Chargaff met Watson and Crick. Chargaff was not impressed with the duo, especially after Crick admitted to not knowing the chemical structures of the nitrogen bases.

WEBIn this animation we'll see the remarkable way our DNA is tightly packed up to fit into the nucleus of every cell. The process starts with assembly of a nucleosome, which is formed when eight separate histone protein subunits attach to the DNA molecule.
All Wound Up: DNA sequencing reveals the 3D structure of our DNA
WEBJan 4, 2018 · DNA adopts a complex 3D structure—like a ball of lint or a tumbleweed—but scientists have only recently begun to determine what these structures look like using new DNA sequencing technology. DNA molecules are composed primarily of four chemicals: adenine (A), tyrosine (T), cytosine (C), and guanine (G).
