adenine, thymine, guanine, and cytosine
Phosphate and sugar make up the sides of a DNA ladder.
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.
The phosphate groups and deoxyribose molecules makes up the DNA ladder.

The Base Pairs
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.
The steps of the DNA ladder are made up of nitrogenous bases. These bases include adenine, thymine, cytosine, and guanine. They pair up in a specific manner where adenine pairs with thymine, and cytosine pairs with guanine.
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 sides of the DNA ladder are composed of alternating sugar (deoxyribose) and phosphate groups, which form the backbone of the molecule. The steps of the ladder are made up of nitrogenous base pairs, specifically adenine paired with thymine and cytosine paired with guanine. These base pairs are held together by hydrogen bonds, creating the double helix structure characteristic of DNA.
The DNA ladder is made of sugar and phosphates.
what are 4 bases that make up 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.
