The bases of DNA are adenine (A), thymine (T), guanine (G), and cytosine (C).

The Human Genome Project (HGP) made its sequence data publicly available to serve as a foundational resource for the global scientific community, ensuring that the fundamental information of the human genome could be used to advance medicine and biological research.12

By providing open access to the three billion chemical base pairs of human DNA, the project enabled researchers to identify genes associated with diseases, facilitating the development of more accurate diagnostics and the emergence of personalized medicine.12

Furthermore, the decision to maintain public access was a critical response to competition from the private sector. In the late 1990s, the enterprise Celera Genomics sought to potentially patent genome sequences, which were viewed as a valuable pharmaceutical resource. By keeping the data public, the HGP ensured that this "treasure trove" of genetic information remained a shared asset for humanity rather than being restricted by private patents, thereby upholding the ethical principle that such fundamental biological knowledge should be accessible to all for the benefit of global health.3
