it is made up of phosphate and purine bases
The hydrogen bonds that "tie" the two DNA strands together; 2 for A and T and 3 for C and G.
DNA has two strands that form a double helix shape. The double helix structure is like a twisted ladder, with two strands of nucleotides connected by hydrogen bonds and coiled around each other.
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.
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.

If you mean the rungs of the twisted ladder model, they are made of the nitrogen bases of both strands held together by hydrogen bonds.

Yes, DNA is double-stranded.There are two strands. Each one is a polymer (series) of nucleotides, and the two strands twine round one another to form the DNA molecule.
