Final answer:
A DNA nucleotide is composed of a nitrogenous base, a deoxyribose sugar, and a phosphate group. The base is attached to the sugar's 1' carbon, and the phosphate is attached to the 5' carbon. The nucleotide is named based on the type of nitrogenous base, which can be adenine, guanine, cytosine, or thymine.
Step-by-step explanation:
The components that make up a DNA nucleotide include a nitrogenous base, a deoxyribose sugar (which is a 5-carbon sugar), and a phosphate group. These components are assembled in the following sequence: the nitrogenous base is attached to the 1' carbon of the deoxyribose sugar, and the phosphate group is connected to the 5' carbon of the sugar. There are four types of nitrogenous bases in DNA: adenine (A) and guanine (G), which are purines with a double ring structure, and cytosine (C) and thymine (T), which are pyrimidines with a single ring structure. The nucleotide is specifically named depending on which nitrogenous base it contains.
