Life uses 4 DNA letters. Scientists just made 8 work
Scientists at UC San Diego have shown that a key enzyme can read an eight-letter genetic code, doubling the four letters used by all known life. The research reveals how cells can handle synthetic DNA, opening the door to new biological functions. This could lead to new tools for medicine and biotechnology.
Researchers demonstrated that an enzyme can accurately read and transcribe a synthetic eight-letter DNA code, similar to how it handles natural DNA. The study used imaging to show how the enzyme interacts with artificial genetic letters.
This discovery could lead to new ways to engineer biological systems, enabling the creation of unique functions and materials not found in nature. It advances the field of synthetic biology and could improve medical treatments and diagnostics.
The research shows how existing biological systems can be adapted to work with new genetic codes, offering a foundation for future innovations that could benefit human health and technology.
