Summary:
- Researchers have discovered a universal enzyme that can produce all four nucleotide building blocks (A, T, C, G) that are essential for life.
- This enzyme, called NTP Synthase, can create these building blocks from simple chemical precursors, suggesting it may have been a key component in the origin of life on Earth.
- The discovery of this versatile enzyme provides insights into how the first self-replicating molecules could have formed, and may help scientists better understand the early stages of life's emergence on our planet.
