What makes up the side of the ladder of a DNA molecule?

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.


What makes up the outside of the dna ladder?

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 double helix looks like a twisted ladder What makes up each rung of the ladder What makes up the sides of the ladder What holds the rungs together at the sides?

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.
