|How is nucleoside can be pyrimidine or purine?|
|Hannah said: (Mar 27, 2014)|
|The question given is the definition of the nucleoside. Therefore, Nucleoside means purine/pyrimidine base+ a sugar which is covalently bonded to the base.|

|Doesn't it mean that purine means a base plus a sugar?|
|Nikhil said: (Nov 9, 2016)|
|Nitrogen base is bound to the sugar by the means of glycosidic bond and the glycosidic bond is a covalent bond so either pyrimidine or purine are bound to the sugar by the means of covalently bound glycosidic bond.|

A purine/pyrimidine is a base while a nucleoside is any of these bases + a pentose sugar. They are bonded by an N-glycosidic bond (nitrogen of base and c1 of sugar).

|Yes, the sugar is covalently bonded to purine/pyrimidine.|
