DNA遗传编码是由两种天然碱基对（A和T，C和G）构成。现在，科学家在《自然》上发表论文，报告他们创造了非天然碱基对，用非天然碱基对构成的DNA成功的融合在大肠杆菌细胞中。在DNA双链之间，四种天然碱基相互配对，形成了DNA的双螺旋结构。加州Scripps研究院的研究人员开发出一对非天然碱基对（d5SICSTP和dNaMT），他们让这两种分子合成在细菌质体DNA中，再将质体植入大肠杆菌。这段带有新字母的DNA成功在细菌中复制还有转录，而且当细菌分裂时，还会带着这段独特的质体一起分裂。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
