| In DNA the bases pair to form a ladder-like structure, with adenine paired with thymine and guanine with cytosine. |
| These data confirm that cycloaddition occurs between the 8,9-double bond of HFQ and the 5,6-double bond of thymine. |
| The nucleotide elements of DNA are adenosine, guanine, cytosine, and thymine, abbreviated A, G, C, and T, respectively. |
| These bases are adenine, cytosine, guanine and thymine and can be represented as A, C, G, and T, respectively. |
| Insertion of the thymine moiety into the angelicin skeleton caused a folding of about 51 of the cyclohexyl moiety. |
| The derivatives of purine are called adenine and guanine, and the derivatives of pyrimidine are called thymine, cytosine and uracil. |
