Deoxyribose versus Ribose sugars

    Ribose is a single-ring pentose [5-C] sugar. The numbering of the carbon atoms runs clockwise, following organic chemistry rules. Note the absence of the hydroxyl (-OH) group on the 2’ carbon in the deoxy-ribose sugar in DNA as compared with the ribose sugar in RNA.
