which nucleotide component contains nitrogen

The nucleotide component that contains nitrogen is the nitrogenous base. These bases are organic molecules that include nitrogen atoms and are classified as either purines (adenine and guanine) or pyrimidines (cytosine, thymine in DNA, and uracil in RNA). The nitrogenous bases are essential for the coding information in nucleotides, while the other components of nucleotides are a sugar molecule and a phosphate group, which do not contain nitrogen.
