Artificially Expanded Genetic Information System (AEGIS) is a synthetic DNA analog experiment that uses some unnatural base pairs from the laboratories of the Foundation for Applied Molecular Evolution in Gainesville, Florida. AEGIS is a NASA-funded project to try to understand how extraterrestrial life may have developed.[1]

The system uses twelve different nucleobases in its genetic code. These include the four canonical nucleobases found in DNA (adenine, cytosine, guanine and thymine) plus eight synthetic nucleobases).[1][2][3][4][5] AEGIS includes S:B, Z:P, V:J and K:X base pairs.[6]
