Adenine,Thymine,Guanine,and Cytosine!
Ladders are constructed of various materials, such as wood, aluminum, or fiberglass. In general, the upright sections and the rungs would be made of the same material. And if you are not sure what rungs are, those are the horizontal parts that you can step on.
The rungs or steps of DNA are made up of nucleotide bases. There are four types of nucleotide bases: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up in a specific way (A with T and C with G) to form the rungs of the DNA ladder.

A DNA strand is made up of alternating sugar (deoxyribose) and phosphate molecules. The nitrogenous bases (adenine, thymine, cytosine, and guanine) are attached to the sugar molecules, forming the "rungs" of the DNA ladder.
A ladder is a vertical or inclined set of rungs or steps used for climbing up or down. Examples of ladders include step ladders, extension ladders, attic ladders, and platform ladders. They are commonly used in construction, maintenance, and firefighting.
The rungs of the DNA ladder are composed of alternating deoxyribose sugar molecules and phosphate groups.
Two strands of nucleotides, paired by weak hydrogen bonds (the rungs) between the bases, from a double-stranded DNA. When bonded in this way, DNA forms a two-stranded spiral, or double helix. Note that adenine always bonds with thymine and cytosine always bonds with guanine.
The rungs of the DNA ladder are made up of nitrogenous bases, specifically adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C). These base pairs are held together by hydrogen bonds, forming the double helix structure of DNA.
Phospate groups and dioxyribose sugars. the "rungs" are made up of the four nitrogen bases--adenine, thymine, guanine and cytosine.
nucleotide
Sugar. The backbone of the DNA molecule is composed of ribose and phosphate, but the bases which make up the "rungs" of DNA are always connected to the sugar. The phosphate is used to bond the sugars together into long strings.
