DNA对我们许多人来说并不陌生,它是携带生命遗传密码的重要载体。但如今,即便如此重要的载体也能被人工合成的物质替代。近日,英国研究人员人工合成了一种名为XNA的物质,XNA链条和DNA链条之间可以互相结合,实现遗传信息的传递,甚至自身的进化,从而参与生命合成的过程。由于XNA已 DNA is familiar to many of us and is an important vehicle for carrying the genetic code of life. But nowadays, even such important carriers can be replaced by synthetic materials. Recently, British researchers synthesized a substance called XNA, XNA chain and DNA chain can be combined with each other to achieve the transfer of genetic information, and even their own evolution, and thus participate in the process of life synthesis. Thanks XNA already
