are made up of three components, a pentose sugar (ribose or deoxyribose), a phosphate group and an organic base which may either be a purine ( adenine or guanine) or a pyrimidine ( cytosine thymine or uracil).This basic structure is found in many important cell molecules such as in ADP, ATP and coenzymes. Nucleotides also form the subunits from whi... Found on http://www.encyclo.co.uk/local/20169
