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.
