All of the components of ribonucleic acid are identical to those of DNA, with only two exceptions. Adenine (sometimes known as vitamin B4) combines with the sugar ribose to form adenosine, which in turn can be bonded with from one to three phosphoric acid units, yielding AMP, ADP and ATP.These adenine derivatives perform important functions in cellular metabolism.

Cytosine is an organic pyrimidine base that has the formula of C 4 H 5 N 3 O and it pairs complementary with guanine in nuclei acids like DNA and RNA. During replication, O 6 alkylG adducts pair with thymine at high frequencies (>80%) instead of with cytosine, due to the disruption of normal hydrogen bond pairing caused by the adduct (see Fig. The single-ring nitrogenous bases, thymine and cytosine, are called pyrimidines, and the double-ring bases, adenine and guanine, are called purines. We have theoretically analyzed AT pairs in which puri Gas-phase clusters of water with DNA bases [guanine (G), cytosine (C), adenine (A), and thymine (T)] are generated via thermal vaporization of the bases and expansion of the resultant vapor in a continuous supersonic jet expansion of water seeded in Ar.
