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.
Two of the four nitrogenous bases make up the rungs on the DNA ladder. They are held together by two hydrogen bonds that occur between the adenosine and the thymine base pairs. Between the cytosine and the guanine there are three.
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 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.
In DNA, the actual nitrogenous base rings make up the "ladder" while the "sides" are made from alternating deoxyribose and phosphate groups.
The rungs or steps of DNA are made up of nucleotide bases. There are four types of nucleotide bases: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up in a specific way (A with T and C with G) to form the rungs of the DNA ladder.
Radioactive nucleotide
The phosphate group is part of the nucleotide. Pentose sugar and Nitrogenous base is part of the parts that make up the nucleotide.
