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 WebAug 23, 2024 · Each DNA strand is built from dNTPs by the formation of a phosphodiester bond, catalyzed by DNA polymerase, between the 3’OH of one nucleotide and the 5’ phosphate of the next. The result of this directional growth of the strand is that the one end of the strand has a free 5’ phosphate and the other a free 3’ hydroxyl group (Figure 2.130).
