A DNA machine is a molecular machine constructed from DNA . Research into DNA machines was pioneered in the late 1980s by Nadrian Seeman and co workers from New York University . DNA is used because of the numerous biological tools already found in nature that can affect DNA, and the immense knowledge of how DNA works previously researched by biochemistry biochemists . DNA machines can be logically designed since DNA assembly of the double helix is based on strict rules of base pairing that allow portions of the strand to be predictably connected based on their sequence. This selective stickiness is a key advantage in the construction of DNA machines. An example of a DNA machine was reported by Bernard Yurke and co workers at Lucent Technologies in the year 2000, who constructed molecular tweezers out of DNA. ref name pmid10949296 cite journal author Yurke B, Turberfield AJ, Mills AP, Simmel FC, Neumann JL title A DNA fuelled molecular machine made of DNA journal Nature volume 406 issue 6796 pages 605 8 year 2000 month August pmid 10949296 doi 10.1038 35020524 url ref The DNA tweezers contain three strands A, B and C.

A DNA bank is a wikt repository repository of DNA , usually used for research. The NIAS DNA Bank, for example, collects the DNA of agricultural organisms, such as rice and fish , for scientific research. Most DNA provided by DNA banks is used for studies to attempt to develop more productive or more environmentally friendly agricultural species. Some DNA banks also store the DNA of rare or endangered species to ensure their survival. The Asia First DNA Bank Establish in Lucknow City Of India And Worlds Second DNA Bank.

Orphan date February 2009 The solenoid defines the packing of DNA as a 30 nm fiber of chromatin and results from the helical winding of at least five nucleosome strands. In eukaryotic cell biology cells , 146 bp of DNA are wrapped approximately 1.76 times around a histone octamer each histone consists of 2 H2A, H2B dimers, and H3, H4 tetramer which together are called a nucleosome. Histone H1 , which is not part of the binding histones, tightens the DNA bound to the eight protein complex. The nucleosomes, which at this point resemble bead s on a string, are further compacted into a helical shape via the NH2 terminal protein interactions of the octameric histones, called a solenoid. DNA packed into solenoids, unlike DNA in nucleosome form, is not Transcription genetics transcriptionally active. With more packing, solenoids are able to become increasingly more packed, forming chromosomes. At this point, solenoids coil around each other to form a loop anywhere from 20 to 80,000 base pairs , followed by a rosette consisting of six connected loops , then a coil, and at last, two chromatids . The end result is the metaphase chromosome . The completely condensed chromatin has a diameter of up to 600 nm.
