| A further possible pathway of guanine quadruplex formation has also been proposed that is essentially a triplex dissociation process. |
| Causes and effects The structure of thalidomide is similar to that of the DNA purine bases adenine and guanine. |
| The derivatives of purine are called adenine and guanine, and the derivatives of pyrimidine are called thymine, cytosine and uracil. |
| These bases are adenine, cytosine, guanine and thymine and can be represented as A, C, G, and T, respectively. |
| Isochores were defined as long genomic segments that are fairly homogeneous in their guanine and cytosine composition. |
| Among the possible geometries, tetraplexes are very stable structures in which the four strands are held together via repetitive guanine tetrads. |
