What forms the sides of DNA ladder?

The sides of the DNA ladder are composed of alternating Phosphate and deoxyribose (sugar) molecules.


How do you describe the basic structure of the DNA molecules?

DNA is composed of two strands of DNA nucleotides, arranged into a double helix, often referred to as a twisted ladder. The sides of the ladder are composed of alternating deoxyribose sugar molecules and phosphate molecules, and the rungs of the ladder are the pairs of nitrogen bases. The two strands of DNA nucleotides are held together by hydrogen bonds which form between the paired nitrogen bases.

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.

Which part of the ladder is made of sugars and phosphates?

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.


Sides of the ladder are formed by?

The DNA ladder is made of sugar and phosphates.
