WebDNA nucleotides assemble in chains linked by covalent bonds, which form between the deoxyribose sugar of one nucleotide and the phosphate group of the next. This arrangement makes an alternating chain of deoxyribose sugar and phosphate groups in the DNA polymer, a structure known as the sugar-phosphate backbone Chargaff's rules WebChemical bonding always lowers the potential energy of the bonded system—we say that a bonded system is “more stable”. Forming a bond releases energy to the surroundings, while breaking a bond requires energy input. In this section, we will examine three important models describing three classes of chemical bonding: ionic, covalent, and ...
