Which component of a DNA nucleotide is a nitrogen-containing base?

Explanation:
DNA nucleotides have three parts: a 5-carbon sugar (deoxyribose), a phosphate group, and a nitrogen-containing base. The base is the component that carries genetic information because its sequence encodes genes and pairs with the complementary base on the other strand (A with T, C with G). The sugar forms the backbone, and the phosphate links sugars together. A mutation is a change in the nucleotide sequence, not a structural component of the nucleotide. An amino acid is a building block of proteins, not part of DNA.
