Describe the structure of the double helix
Web1. A molecule of DNA consists of two strands that form a double helix structure. DNA is a macromolecule consisting of two strands that twist around a common axis in a shape … WebA double helix resembles a twisted ladder. Each ‘upright’ pole of the ladder is formed from a backbone of alternating sugar and phosphate groups. Each DNA base? (adenine, cytosine, guanine, thymine) is attached to the backbone and these bases form the rungs. There are ten ‘rungs’ for each complete twist in the DNA helix.
