The sides of the DNA ladder, or double helix, are composed of alternating sugar and phosphate molecules. Specifically, the sugar is deoxyribose, which is connected to phosphate groups, forming the backbone of the DNA structure. These sugar-phosphate backbones provide stability and support for the nitrogenous bases that pair in the center of the ladder.
A ribose sugar linked by phosphate groups.
The structure of DNA can be compared to a ladder. 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). (A grouping like this of a phosphate, a sugar, and a base makes up a subunit of DNA called a nucleotide.) These bases make up the "rungs" of the ladder, and are attached to the backbone where the deoxyribose (sugar) molecules are located.
DNA is made up of deoxyribose, phosphate, and nitrogen bases (adenine, thymine, cytosine, and guanine). The rungs of the ladder are made of two bases joined together with either two or three weak hydrogen bonds.
The Sides of this ladder equate to the Dna's Sugar-Phosphate Backbone; the Rungs of this ladder equate to the Hydrogen-bonding that takes place between base pairs.
The sides of the DNA latter consist of the sugar deoxyribose and phosphates. The bond between the latter and the nitrogen bases together is known a a nucleotide. Nucleotides are molecules that make up the structure of DNA and RNA.

The former has four sides while the latter has three sides.
The former has 4 sides while the latter has 6 sides.
Chemical phosphate and sugar backbone
The sides of the DNA ladder, or double helix, are composed of alternating sugar and phosphate molecules. Specifically, the sugar is deoxyribose, which is connected to phosphate groups, forming the backbone of the DNA structure. These sugar-phosphate backbones provide stability and support for the nitrogenous bases that pair in the center of the ladder.
Backbone. A deoxyribose sugar and a phosphate group.
A ribose sugar linked by phosphate groups.
The sides of the DNA double helix are formed by alternating sugar (deoxyribose) and phosphate molecules, which make up the backbone of the structure. The sugar-phosphate backbone provides stability and support for the nitrogenous bases in the center of the helix.
A square or a diamond. The latter is properly called a rhombus.

I'm assuming you mean the double helix "ladder-like" formation of a strand of DNA. The sides of the structure are essentially a phosphate-deoxyribose backbone.
