The single-ring nitrogenous bases, thymine and cytosine, are called pyrimidines, and the double-ring bases, adenine and guanine, are called purines. In this work, we report on a photoionization study of the microhydration of the four DNA bases. The main difference between adenine and guanine is that adenine contains an amine group on C-6, and an additional double bond between N-1 and C-6 in its pyrimidine ring whereas guanine contains an amine group on C-2 and a carbonyl group on C-6 in its pyrimidine . Antibody Structural Components & Function | Chains & Domains: Overview & Examples. Or, more simply, C bonds with G and A bonds with T. It's called complementary base pairing because each base can only bond with a specific base partner. If you try to orient the two strands parallel to each other, the sugar ends of the polynucleotides are both at one end and the phosphate groups are at the other end. [3] Similarly, the simple-ring structure of cytosine, uracil, and thymine is derived of pyrimidine, so those three bases are called the pyrimidine bases. Guanine has the molecular formula C 5 H 5 N 5 O with molecular weight of 151 am u. Adenine is C 5 H 5 N 5 (molecular weight 135 am u), cytosine is C 4 H 5 N 3 O (molecular weight 111 am u) and thymine is C 5 H 6 N 2 O 2 (molecular weight 126 am u). d) DNA synthesis On the other hand, guanine forms a pair with cytosine in both RNA and DNA. Both adenine and guanine are purines. Learn about the DNA bases adenine, thymine, guanine, and cytosine. Nitrogenous Bases in DNA & RNA | What is a Nitrogen Base Pair? Its chemical structure is shown below. Its symbol is T and it is found in DNA but not RNA. Only pairing purine with pyrimidine ensures a constant width for the DNA. A nucleotide is made up of a sugar (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), thymine (T), guanine (G) or cytosine (C). Several groups are working on alternative "extra" base pairs to extend the genetic code, such as isoguanine and isocytosine or the fluorescent 2-amino-6-(2-thienyl)purine and pyrrole-2-carbaldehyde.
