    genetic code is stored in DNA. It consists of four nucleotides, represented by four different letters. U.S. researchers have synthesized a new eight-letter DNA structure. Its information storage density is doubled, and it is expected to be used in synthetic biology and other fields in the future.
    DNA is a complex molecule that stores and transmits genetic information and is the genetic material basis of earth creatures, consisting of four nucleotides, namely adenine, thymus, cytosine, and ostrich, expressed in letters A, T, C, and G.
    the team, led by Steven Benner of the American Foundation for Applied Molecular Evolution, reported in a new issue of Science that the new DNA molecular system they synthesized is the biggest difference between natural DNA, which has eight rather than four life information components. In addition to containing four natural nucleotides, such as adenine, there are four other man-made information units with similar structures. Together, they form a double helix structure that stores and transmits information.
    researchers named the molecular system "Hachimoji", which means "eight letters" in Japanese.
    it is worth noting that the synthesis of new DNA structures means that the natural DNA structures on Earth may not be the only infrastructure for life. The team says the scope of future human searches for extraterrter life could also be expanded appropriately.
    team carefully analyzed the shape, size and structure of the artificial DNA, "which will help expand our understanding of the molecular structure of extraternial life used to store genetic information," Benner said.
    , NASA's mission in planetary science, said the exploration of life was an important goal of NASA's planetary science mission, and that the research had developed effective tools to "expand our search for extraterrestate life." (Source: Xinhua News Agency, Zhou Zhou)
