The DNA ladder is made of sugar and phosphates.
The sides of the ladder are made up of alternating deoxyribose sugar and phosphate molecules. The steps or rungs of the ladder are made up of nitrogenous bases held together by hydrogen bonds.
The sugar-phosphate backbone of DNA is made up of alternating sugar (deoxyribose) and phosphate molecules. These molecules form the "rungs" of the DNA ladder, connecting the nitrogenous bases that make up the steps of the 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.

You could use "ladder" in a sentence like this... I climbed up the ladder to get in my attic. My dad owns a ladder. We keep our ladder in our backyard. I climbed up the ladder. Do you own a ladder?

In you ladder analogy it would be the rungs. About half is each rung is one base (the other half being is pair obviously)
Each rung of the DNA double helix is made up of a pair of nitrogenous bases (adenine-thymine or guanine-cytosine). The sides of the ladder are made up of alternating sugar (deoxyribose) and phosphate molecules. Hydrogen bonds hold the nitrogenous bases of the rungs together, creating the structure of the DNA double helix.
