The DNA ladder is made of sugar and phosphates.
nucleotitdesÂ
sugar phospate
The sides of the DNA ladder are composed of alternating Phosphate and deoxyribose (sugar) molecules.
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 sequence of the nitrogenous bases, which are the 'rungs' of the DNA 'ladder' are what give DNA its specificity.
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.

No ones DNA is ever exactly alike due to the countless combos that are possible to be made in the helix ladder
