Purines are the heterocyclic organic compounds which have pyrimidines ring in them. 5-Fluorouracil enters the biosynthetic chain but forms an inactive complex which blocks the synthesis of pyrimidine nucleotides and hence inhibits DNA synthesis in cancer cells. Uracil, a nitrogenous base found in RNA, is a pyrimidine. Answer. Although U/A is not a normal base pair in DNA, it is not mutagenic. Therefore, U and A pairs with each other by the formation of two hydrogen bonds. Adenine and guanine are purine bases while cytosine, thymine and uracil are pyrimidine bases. Flurouracil is a drug that is similar in structure to the pyrimidine uracil. It is denoted as U. all of the above One of the three diazines, it has the nitrogen atoms at positions 1 and 3 in the ring. is a pyrimidinec. These ring structure are known as heterocylic as they are made of atoms of two element known as nitrogen and carbon. The other diazines are pyrazine and pyridazine. Useful mnemonics to remember these bases are: 1. The others are adenine, cytosine, and guanine. The three pyrimidine nitrogenous bases, thymine (T), cytosine (C), and uracil (U), are modified forms of the aromatic compound pyrimidine. The base is either a purine base (adenine or guanine) or a pyrimidine base (uracil, thymine or cytosine). They are called nitrogenous bases as they contain nitrogen and carbon atoms in the ring(s).
