WebBoth RNA and DNA are large polymers containing repeating structural units, or monomers, called nucleotides. 12.1 Components of Nucleic Acids A nucleotide is composed of three units: an organic base, a sugar, and a phosphate. A) Organic Bases The organic bases found in nucleic acids are derivatives of pyrimidine or purine. WebWhat makes DNA molecules so stable? The main bonding in DNA which renders the double helix structure so stable is that of hydrogen bonds. Between the complementary base …
WebDepartment of Chemistry College of Natural & Agricultural Sciences WebAmines, on the other hand, are known as the organic bases since the lone pair on the nitrogen can be protonated forming relatively stable conjugate acids with p K a ~ 11.
