Self-assembled molecules nucleotide systems

Hence, the bottom-up procedures from a molecule to create new structures have become an important approach. This approach has already been used by Nature. Most of the structures of biological systems have been made by self-assembly and self-organization of specific molecules. The tobacco mosaic virus, for example, is rod-shaped—300 nm long and 18 nm in diameter—and has a mass of about 40,000 kDa [2]. The 2130 identical subunits in the protein coat are closely packed in a helical array around an RNA molecule consisting of 6390 nucleotides. Dissociated tobacco mosaic virus subunits and RNA can reassemble, under suitable conditions, into a virus that is identical with the original in structure and function.
