Group the following as nitrogenous bases and nucleosides:
Adenine,Cytidine,Thymine,Guanosine,Uracil and Cytosine.

(N/A) Nitrogenous bases are organic molecules containing nitrogen that form the building blocks of nucleotides. In the given list,adenine,thymine,uracil,and cytosine are nitrogenous bases.
Nucleosides are compounds formed by the attachment of a nitrogenous base to a sugar molecule (ribose or deoxyribose). In the given list,cytidine (cytosine + sugar) and guanosine (guanine + sugar) are nucleosides.
