Which of the following options correctly represents the sequence of a nitrogenous base, its corresponding nucleoside, and its corresponding nucleotide, in that exact order?

Step-by-step solution

A nitrogenous base is a heterocyclic compound (e.g., Adenine, Guanine, Cytosine, Uracil, Thymine). When a nitrogenous base is attached to a pentose sugar, it forms a nucleoside (e.g., Guanosine, Thymidine). When a phosphate group is esterified to the sugar of a nucleoside, it forms a nucleotide (e.g., Guanylic acid, Uridylic acid). Therefore, the correct sequence is Guanine (base), Guanosine (nucleoside), and Guanylic acid (nucleotide). Glycine is an amino acid, not a nitrogenous base. Thymine, Thymidine, and Uridy
