Nucleotide is a monomer (repeating small unit) of DNA, RNA. It also constitutes ATPs, GTPs, ADPs and so on. Nucleotde consists of a sugar pentose, nitrogen base and and phosphate group. Sugar can be either ribose or deoxyribose (note that deoxyribose is sugar, but not a carbohydrate). Nitrogen base can be either derivative of pyrimidine - a heterocycle ring - which are Thymine, Cytosine and uracile; or purine rings - two heterocycle rings joined together - which are guanine and adenine. Nitrogenous bases are attached to 1'-carbon atom in the sugar. Phospate group is attached to the 5' carbon via phosphoester bond. That's all, mi amigo. Qosh bol
