The sides (uprights) of the DNA molecule are composed of alternating deoxyribose sugar molecules and phosphate molecules.

The backbone of DNA is made up of alternating sugar (deoxyribose) and phosphate molecules. The bases adenine, thymine, guanine, and cytosine are attached to the deoxyribose sugars, forming the rungs of the DNA helix.
The upright sides of the ladder-like model of DNA consist of alternating sugar (deoxyribose) and phosphate molecules, which make up the backbone of the DNA molecule. The sugar-phosphate backbone provides structural support and stability to the DNA molecule.
The two molecules that make up the sides of the DNA molecule are deoxyribose sugar and phosphate groups. These molecules alternate to form the sugar-phosphate backbone of the DNA double helix structure.
DNA molecules contain genetic information in a double-stranded helical structure, while daughter DNA molecules are formed during DNA replication and consist of two identical copies of the original DNA molecule. Daughter DNA molecules are produced through a semi-conservative process where one strand of the original DNA molecule is conserved in each daughter molecule.

Two double stranded DNA molecules are created by the process of DNA replication.
