This image illustrates the chemical structures of the five main nucleobases found in DNA and RNA. The pyrimidines, thymine (DNA), uracil (RNA), and cytosine are shown on top while the purines, adenine ...

There are plenty of unanswered questions about the origin of life on Earth. But the research community has largely reached consensus that one of the key steps was the emergence of an RNA molecule that ...

Adenine was first discovered in 1885 by the German physiologist Albrecht Kossel. He isolated adenine from the pancreas of oxen and named it "adenine" derived from the Greek word "aden," meaning gland.

For the first time, researchers have succeeded in developing an artificial DNA base pair that is based on a different chemical force than natural genetic material. While the common natural DNA ...
