the physical structure of DNA which is similar in all organisms. The DNA molecule is shaped like a twisted rope ladder, called the double helix. The rungs of the ladder are made up of four chemical compounds. This structure allows for easy replication of the molecule.

Two strands of DNA coiled about a central axis, usually a right-handed helix. The two sugar phosphate backbones wind around the outside of the bases (A = adenine, G = guanine, T = thymine, C = cytosine) and are exposed to the solvent. The strands are antiparallel, thus the phosphodiester bonds run in opposite directions. As a result the structure has major and minor grooves at the surface. Each adenine in one strand of DNA is hydrogen bonded to a thymine in the second strand; each guanine is hydrogen bonded to a cytosine. This is the case throughout the coupling of the two strands.

The structure of DNA described and discovered by Watson and Crick.

Structural arrangement of DNA, which looks something like an immensely long ladder twisted into a helix, or coil. The sides of the "ladder" are formed by a backbone of sugar and phosphate molecules, and the "rungs" consist of nucleotide bases joined weakly in the middle by hydrogen bonds.

A term often used to describe the configuration of the DNA molecule. The helix consists of two spiraling strands of nucleotides (a sugar, phosphate and base) joined crosswise (like rungs on a ladder) by specific pairing of the bases.
