All known life uses 4 DNA letters; UC San Diego showed an existing bacterial enzyme can accurately read and transcribe 8, doubling the genetic alphabet with synthetic letters
- Representative image of DNAAll life on Earth, from bacteria to blue whales, writes its genetic instructions using the same four-letter alphabet.
- These four DNA bases, usually referred to as A, T, C and G, pair up in predictable ways to store and pass on the information needed for life.
- Now, researchers at UC San Diego have taken a bold step beyond that universal code.
