Verified step by step guidance

Understand the basic structure of nucleotides: a nucleotide consists of three components - a nitrogenous base, a five-carbon sugar, and one or more phosphate groups.

Recall that DNA nucleotides contain the sugar deoxyribose, while RNA nucleotides contain ribose. This difference is key to identifying DNA nucleotides.

Identify the nitrogenous bases found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G). RNA contains uracil (U) instead of thymine.

Analyze each option by checking the sugar and the nitrogenous base: for example, 'Deoxyadenosine monophosphate' contains deoxyribose (indicating DNA) and adenine, making it a DNA nucleotide.

Confirm that other options like 'Adenosine triphosphate', 'Cytidine diphosphate', and 'Uridine triphosphate' contain ribose or bases typical of RNA, so they are not DNA nucleotides.
