John Sutherland from the University of Manchester, UK, may have found the correct combination of primordial conditions for producing RNA. These findings may lead to a refinement of scientific theories related to the transition of natural nonbiotic molecules into the first elements of biological life.

From the paper entitle "Synthesis of activated pyrimidine ribonucleotides in prebiotically plausible conditions" in the peer-reviewed ''Nature'' journal, the authors document their methodologies. The scientists claimed to be able to repeatably create RNA structures from a joint precursors solution (pairing the bases and sugars in the molecule), a good blast of UV light, and 5 ingredients thought to be in abundance on the pre-biotic earth. The news has been hyped, "It will stand for years as one of the great advances in prebiotic chemistry." <ref>[http://news.yahoo.com/s/afp/20090513/sc_afp/sciencebiologylife_20090513210508 RNA] AFP.

May 13, 2009</ref> While RNA generation has been happening for some time, no scientist has yet found experimental proof of DNA synthesis. DNA, which is found in all but the most simple lifeforms, has a more complex structure with its iconic double helix design. If or until scientist develop concepts of natural DNA synthesis, there will remain many more unanswered questions for micro biologists everywhere.
