| Causes and effects The structure of thalidomide is similar to that of the DNA purine bases adenine and guanine. |
| In the GART locus, however, simultaneous transcription of the purine gene and the intronic gene seems possible. |
| The derivatives of purine are called adenine and guanine, and the derivatives of pyrimidine are called thymine, cytosine and uracil. |
| The chemical and biological effects of UV radiation on purine and pyrimidine nucleosides and nucleotides have been the subject of many studies. |
| Uric acid is a byproduct of the metabolism of purine, a protein found particularly in red meat and offal, game, seafood and alcoholic drinks. |
| Two of these, adenylate kinase and purine nucleoside phosphorylase, contain potential critical building blocks. |
