佛洛伊德 E. 罗姆斯柏格: 人造 DNA 的可能性

人造 DNA 的可能性

历史上所有的活细胞都是四个字母的基因所产生出来的结果：A、T、C和G——DNA的基本单元，但现在这一历史要改写了。在这场富有远见的演说中，合成生物学家佛洛伊德 E. 罗姆斯柏格向大家介绍了用六个字母的DNA所创造出来的生物体，这是史无前例的——四个天然的字母加上两个人造的字母，X和Y——他也探讨了这项突破会如何挑战我们对于大自然造物的了解。

Scientists have created living bacteria whose DNA includes two new man-made letters, bringing the genetic alphabet from four to six letters for the first time. This breakthrough enables cells to store more information and build proteins with new, unprecedented properties. By introducing these synthetic letters, researchers challenge the idea that life is limited to nature’s original design. The discovery opens possibilities for new medicines, materials, and ways to understand what life can be.
