I'll assume you're talking about the "double helix" structure which looks like a twisted ladder, rather than an electrophoresis gel plate film.
DNA is a double stranded sequence of nucleic acids... on one side a "protein code" is made using Adenine, Thymine, Guanine, Cytosine.
On one side, each of these nucleic acids is punctuated by a phosphate group.
Each "rung" on the ladder is formed by hydrogen bonds between one side and the other. Adenine bonds to Thymine and Guanine to Cytosine.
Hydrogen bonds are formed when an exposed hydrogen atom, which is covalently bonded to an electronegative atom, is in close proximity to another exposed electronegative atom. This happens because the hydrogen atom has a relatively positive charge and the juxtaposed electronegative atom is relatively... well, negatively charged.

What makes up the rungs of the DNA ladder?
Adenine,Thymine,Guanine,and Cytosine!
What are the 4 bases the make up the rungs of the DNA ladder?
what are 4 bases that make up the rungs of the DNA ladder
What 3 parts make up the rungs of the DNA ladder?
The rungs of the DNA ladder are composed of alternating deoxyribose sugar molecules and phosphate groups.
What two chemicals make up the rungs of the DNA ladder?
phosphate and sugar
What is the rung of the DNA ladder?
The rungs that are in the DNA ladder molecule are nucleotides. They are adenine, guanine, thymine and cytosine. Deoxyribose and phosphate make up the backbone of the molecule.
What makes up the side of the DNA ladder?
Phospate groups and dioxyribose sugars. the "rungs" are made up of the four nitrogen bases--adenine, thymine, guanine and cytosine.
What are the four bases of making up the rungs of the DNA ladder?
thymines, guanines, adenines, and cytosines
What molecules make up the rungs of a DNa ladder?
purines, pyrimidines, nucleotides and nitrogen bases.
What four molecules make up the rungs of the ladder?
What four molecules make up the rungs of the ladder
What makes up the rungs of the ladder of DNA?
The nitrogenous bases Adenine, Thymine, Guanine, and Cytosine Adenine and Thymine are always together and Cytosine and Guanine are always together.
What are the sides of the DNA ladder composed of?
The sides of the DNA ladder is composed of sugar and phosphate. 4 bases that make up the rungs of the DNA ladder are A, T, G, and C. The shape of the DNA is a double helix or twisted ladder.
