the "backbone" of the DNA molecule is made up of 2 alternating components , what are these called ?

It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).

The "backbone" of the DNA molecule is made up of 2 alternating components called the sugar and the phosphate. Together these make the sugar-phosphate backbone of DNA.

How is the backbone of DNA formed?

  • The DNA molecule is made up of two strands that coil around each other to form a double helix structure.
  • The backbone of each strand is made up of sugar (deoxyribose) and phosphate groups that alternate.
  • Two linear sugar-phosphate backbones that run opposite each other and twist together in a helical shape generate the molecular double-helix shape in double-stranded DNA.
  • Because the sugar-phosphate backbone is negatively charged and hydrophilic, the DNA backbone can form water bonds.
  • Each sugar has one of four bases attached to it: adenine (A), cytosine (C), guanine (G), and thymine (T).
