The DNA ladder is made of sugar and phosphates.
In a typical organism, DNA will be double stranded and wound into a right handed helix (B form DNA). In this case, the nucleic bases will be on the inside, with the DNA 'backbone' surrounding them. Pointing away from the helix are phosphate groups, made of oxygen and phosphorous. These are attached to deoxy-ribose sugars, which is the other component of the backbone.
Sugar & phosphate
adenine, thymine, cytosine, and guanine.
phosphate :]
The sides of the DNA ladder is composed mainly of deoxyribose. Nitrogen is the base in the ladder. Answer from a workshheet and project of creating a model of one.
Hydrogen bonds
no thing else but PHOSPHATE And SUGAR :)
Deoxyribose, which is a pentose, and a phosphate group. These two molecules together form the two sides of the DNA.

A sugar (deoxyribose) and a phosphate.
The sides of a DNA ladder is made up of "sugars and phosphates".

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 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.
alternating deoxyribose sugar molecules and phosphate groups
There are four bases in a DNA "ladder"... It is called a ladder because of the "two sides" and the bases... In DNA replication, they obviously replicate and the two sides are replicated as are the bases. (A,T,C,G)
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 DNA ladder is made of sugar and phosphates.
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.

what holds the sides of the DNA ladder together
Phosphate and sugar make up the sides of a DNA ladder.
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.
Phosphates and Sugars formthe sides of the DNA ladder~
alternating deoxyribose sugar molecules and phosphate groups
The backbone of the DNA molecule is made up of a sugar (deoxyribose) bonded to a phosphate group bonded to another sugar and then another phosphate and so on. These are very strong covalent bonds that are not easily broken.
