@viralsparkdaily: Scientists doubled life’s genetic code from 4 letters to 8—and nature’s enzymes read it effortlessly. 🧬💻 In a milestone for synthetic genomics published by UC San Diego, researchers bypassed a major biological barrier: The 4-Letter Limit: All known life on Earth is written using just four DNA letters: A, T, C, and G. The 8-Letter Alphabet: Scientists integrated four additional synthetic chemical bases, doubling the genetic alphabet to create an expanded "Hachimoji" code capable of storing vastly richer biological data. No Redesign Needed: In a major surprise, natural bacterial enzymes read and transcribed this synthetic 8-letter DNA into RNA with near-flawless accuracy, opening the door to engineered super-enzymes and DNA data storage. Source: UC San Diego / The Times of India / PNAS — "All known life uses 4 DNA letters; UC San Diego showed an existing bacterial enzyme can accurately read and transcribe 8."
