Researchers at The Ohio University have uncovered the mechanism by which thymine and guanine, the most commonly mutated bases in DNA, become damaged. The study, which was recently published in the ...

EurekAlert!: Discovery of a hidden mechanism in DNA damage: Singlet oxygen generates abasic sites
Discovery of a hidden mechanism in DNA damage: Singlet oxygen generates abasic sites
There are four bases: Adenine and Guanine (purines); Cytosine and Thymine (Pyrimidines). Purines have two carbon-nitrogen rings while pyrimidines have a single carbon-nitrogen ring. Thus, there are ...
Chemical structure of guanine, showing its double-ring purine structure and the functional groups involved in hydrogen bonding with cytosine. (Image: Public Domain) Guanine has the chemical formula ...
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 ...

MSN: Expands the genetic alphabet: Artificial DNA base pair uses halogen bonds to form stable structures
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 ...
