deoxyribonucleic acid: an extremely long, double-stranded nucleic acid molecule arranged as a double helix that is the main constituent of the chromosome and that carries the genes as segments along its strands: found chiefly in the chromatin of cells and in many viruses. ...
Here we show that a chiral biological molecule, a DNA or RNA duplex rotates unidirectionally at billions of revolutions per minute when an electric field is applied along the duplex, with the rotation direction being determined by the chirality of the duplex. The rotation is found to be powered...
Watson and Crick were not the discoverers of DNA, but rather the first scientists to formulate an accurate description of this molecule's complex, double-helical structure. Moreover, Watson and Crick's work was directly dependent on the research of numerous scientists before them, including Friedr...

DNA is the molecule that stores and transmits genetic information in biological systems. The field of DNA nanotechnology takes this molecule out of its biological context and uses its information to assemble structural motifs and then to connect them together. This field has had a remarkable impact...
The structure of the DNA double helix, with its complementary base-pairing, is one of the greatest discoveries in biology in the 20th Century. It was also most dramatic, since, quite unexpectedly, the structure itself pointed to the way in which a DNA molecule might replicate itself, and ...
the double helix unwinds and each separated strand is used to synthesize a new strand. As the new strands form, bases are paired together until two double-helix DNA molecules are formed from a single double-helix DNA molecule. DNA replication is required for the processes ofmitosisandmeiosisto...
This section provides a quick introduction of the primary structure of a DNA (Deoxyribonucleic Acid), which is a double helix formed by the backbones of two complementary DNA sequences paired together.
In a double helix DNA molecule normally found in all plants and animal, each successive base pair in the stack turns A)36 ͦ in a clockwise direction.B)36 ͦ in an anticlockwise direction.C)360 ͦ in a clockwise direction.D)360 ͦ in an anticlo
