Pentose sugars and Phosphate groups
The three parts that make up nucleotides are a phosphate molecule, a 5-carbon ribose sugar and a nitrogenous base. DNA and RNA make up nucleotide chains.
A phosphodiester linkage forms the backbone of a nucleic acid by connecting the 3' carbon of one nucleotide to the 5' carbon of another nucleotide in a chain. This linkage creates a sugar-phosphate backbone that provides stability to the nucleic acid structure.
The structure of a DNA molecule is made up of three things: a sugar-phosphate backbone, nucleotide bases (adenine, thymine, cytosine, and guanine), and hydrogen bonds that form between the bases. These components form the double helix shape of the DNA molecule.
When bonded together chemically, deoxyribose phosphate and an adenine molecule make up a nucleotide, which is a building block of DNA. This nucleotide contributes to the structure of the DNA molecule by providing the adenine base that pairs with thymine to form the rungs of the DNA ladder.
The nitrogenous base can differ from one nucleotide to another. It can be adenine, guanine, cytosine, or thymine (in DNA) or uracil (in RNA). The sugar and phosphate components remain the same in all nucleotides.

The two components that make up the nucleotide backbone are the sugar molecule, which is either ribose in RNA or deoxyribose in DNA, and the phosphate group. Together, they form the repeating structure that provides the backbone for the nucleic acid strand.

A nucleotide is made of three parts. Those parts are: a five carbon ribose sugar, a phosphate molecule, and a nitrogenous base (adenine, guanine, cytosine, or uracil).

The sugar-phoshate part is what makes up the backbone, ribose in RNA and 2-Deoxyribose in DNA with a single phosphate group per nucleotide.
They consist of the extremely selective, in terms of their interactions, biomoleculesthat make all of the several [the phosphate sugar backbone and the nucleotide cross-base] parts of Dna.
