DNA is used by researchers as a molecular tool to explore physical laws and theories, such as the ergodic theorem and the theory of elasticity.

The unique material properties of DNA have made it an attractive molecule for material scientists and engineers interested in micro- and nano-fabrication.

Each nucleotide is composed of one of four nitrogen-containing nucleobases—either cytosine (C), guanine (G), adenine (A), or thymine (T)—and a sugar called deoxyribose and a phosphate group.

The two strands of DNA run in opposite directions to each other and are thus antiparallel.

DNA was first isolated by Friedrich Miescher in 1869.

Its molecular structure was identified by James Watson and Francis Crick in 1953, whose model-building efforts were guided by X-ray diffraction data acquired by Rosalind Franklin.

Within the eukaryotic chromosomes, chromatin proteins such as histones compact and organize DNA.

These compact structures guide the interactions between DNA and other proteins, helping control which parts of the DNA are transcribed.
