Why Probing This New Artificial DNA Molecule Could Help Us Discover Aliens
It has been more than 65 years since James Watson and Francis Crick, working with Rosalind Franklin and Maurice Wilkins discovered that DNA – the basic chemical information code of all life forms – has a double helical structure that played an important role in its function. In a monumental achievement on this journey, scientists funded by NASA and led by the Foundation for Applied Molecular Evolution in the US have synthesized a new stable version of DNA with eight base molecules, compared to the form containing four found on earth. This study is remarkable to me because it has proved that there is nothing particularly unique about the DNA found on Earth, and that there could be other stable forms in the universe that have different combinations of other molecules.
