Successfully synthesized the world's first artificial DNA molecule

Recently, Japanese chemists have successfully synthesized the world's first artificial DNA molecule - almost all of the components that make up this DNA molecule are created in the laboratory. This achievement can bring about future advances in gene therapy, the ability to create nano-sized computers and other high-tech devices.

In this new study, Masahiko Inouye and colleagues note that scientists have been trying for years to develop many types of artificial DNA to expand their incredible information storage capabilities.

In the genetic structure of all life forms, DNA molecules use four basic nucleotides (A, T, G, X) to build and encode all types of proteins that work and grow in cells . Until this achievement was achieved, scientists around the world were only able to create DNA molecules with one or more artificial ingredients by manual methods, including four mechanical components. copy.

Scientists use high-tech devices to assemble four groups of nucleotide components (A, T, G, X) that combine to form a completely new double helix DNA sequence, these 4 types of components. derived from sugar compounds in natural DNA molecules.

The authors say that, like a natural DNA molecule, the structure of artificial DNA also follows the rule of right-hand, sometimes in the form of an undeniable three-component topology. The high steady state and the unique chemical structure of this artificial DNA promise unprecedented prospects in the field of manufacturing and application of new materials through biotechnology.
