WebJul 24, 1996 · Inspection of the most stable tautomeric forms for the neutral and protonated nucleic acid bases allows rationalization of the formation of unusual DNA structures like the triple helix. Tautomerism and protonation of guanine and cytosine in the gas phase and in aqueous solution have been examined by theoretical methods. WebIsocytosine is a structural analogue of cytosine and provides a unique oppor-tunity to study hydrogen bonding interactions, because the two stable tautomers of isocytosine (1,2-I and 2,3-I, Fig. 1) can form hydrogen-bonded dimers in the same way as the guanine and cytosine canonical base pair. The hydrogen-bonded
WebIn the remaining 30% half will be Cytosine (15%) and remaining half will be Guanine(15%). The amount of Adenine is equal to thymine as Adenine always forms bond with Thymine. So if there are 10 Adenines there will be 10 Thymines. In the same way number of Guanine will be equal to number of Cytosine. Adenine-35%. Thymine-35% Guanine-15% Cytosine ...
