1
Understand the structure of a nucleotide: A nucleotide consists of three components - a nitrogenous base, a five-carbon sugar (ribose or deoxyribose), and one or more phosphate groups.
Identify the components of each option: Analyze each given option to determine if it contains all three components of a nucleotide.
Examine 'Adenosine monophosphate': It contains adenosine (a nitrogenous base and sugar) and one phosphate group, making it a nucleotide.
Examine 'Cytidine triphosphate': It contains cytidine (a nitrogenous base and sugar) and three phosphate groups, making it a nucleotide.
Examine 'Adenosine': It contains only adenosine, which is a nucleoside (nitrogenous base and sugar) without any phosphate group, thus not a nucleotide.
