In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

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 ...
