Phospate groups and dioxyribose sugars. the "rungs" are made up of the four nitrogen bases--adenine, thymine, guanine and cytosine.
Phosphate and sugar make up the sides of a DNA ladder.
The phosphate groups and deoxyribose molecules makes up the DNA ladder.

The Base Pairs
The steps of a DNA ladder are made up of alternating sugar (deoxyribose) and phosphate molecules. The side railing of the ladder is composed of nitrogenous bases (adenine, thymine, cytosine, and guanine) that connect the two strands of the DNA molecule.
adenine, thymine, guanine, and cytosine
The sides of a DNA molecule are made up of alternating sugar (deoxyribose) and phosphate molecules, forming the backbone of the DNA strand. The bases (adenine, thymine, cytosine, and guanine) are attached to the sugar molecules and form the rungs of the ladder structure through hydrogen bonds.
The outside of the DNA ladder is made up of a sugar-phosphate backbone. The sugar in DNA is deoxyribose, which alternates with phosphate groups to form the backbone. The nitrogenous bases are attached to this sugar-phosphate backbone on the inside of the ladder.
The DNA ladder is made of sugar and phosphates.
what are 4 bases that make up 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.
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.
