Thanks to a gentler extraction technique, scientists have finally detected cytosine and thymine in meteorites, completing the set of bases required to make up DNA and RNA. Using cold water instead of acid in the extraction process keeps these fragile bases intact. These bases — biological compounds containing nitrogen — come together to form DNA and RNA, the building blocks of life, which lends credence to the theory that the basic components of life did not arise from a primordial soup, but fell from outer space through meteorites.
