Deoxyribose is a five-carbon sugar that forms a critical component of the nucleotide structure in deoxyribonucleic acid (DNA), with each nucleotide comprising a deoxyribose sugar, a phosphate group, and one of four nitrogenous bases: adenine, guanine, cytosine, or thymine. The monomeric units of nucleic acids are nucleotides. The monomers of DNA, the deoxyribonucleotides, each consist of the pentose sugar 2′-deoxyribose covalently bonded to a purine or pyrimidine base, to form a ‘nucleoside’, as in deoxythymidine, the deoxyribonucleoside of thymine: DNA and RNA use a ribose sugar as a main element of their chemical structures, ribose sugar used in DNA is deoxyribose, While RNA uses unmodified ribose sugar.
Ribose and Deoxyribose From the fig above we can see that the principal difference between the two molecules is the presence of OH in ribose (2' tail) and absence in deoxyribose.
