史上所有的活細胞都是四個字母的基因所產生出來的結果：A、T、C 和 G —— DNA的基本單位。但，現在有所改變了。在這場有遠景的演說中，合成生物學家佛洛伊德 E. 羅姆斯柏格向大家介紹用六個字母的 DNA 所創造出來的生物體，這是史無前例的——四個天然的字母加上兩個人造的字母，X 和 Y ——他也探討了這項突破會如何挑戰我們對於大自然設計的了解。

人造 DNA 的根本可能性

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.
