WebAll four nucleotides (A, T, G and C) are made by sticking a phosphate group and a nucleobase to a sugar. The sugar in all four nucleotides is called deoxyribose. It’s a cyclical molecule—most of its atoms are arranged in a ring-structure. The ring contains one oxygen and four carbons. http://www.untergasser.de/lab/protocols/separate_rna_and_dna_v1_0.htm term akrasia
