Deoxyribonucleotide vs. Ribonucleotide: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on January 27, 2024
Deoxyribonucleotides form DNA with a missing oxygen atom in the sugar, while ribonucleotides form RNA and have an extra oxygen.

Key Differences

Deoxyribonucleotides contain deoxyribose, a sugar with one less oxygen atom, while ribonucleotides contain ribose, which has an extra oxygen atom in its sugar structure.
Deoxyribonucleotides are the building blocks of DNA, responsible for storing genetic information. Ribonucleotides, on the other hand, form RNA, which plays various roles including protein synthesis and gene regulation.
The absence of an oxygen atom in deoxyribonucleotides makes DNA more chemically stable than RNA, which is made up of ribonucleotides.
Both deoxyribonucleotides and ribonucleotides contain nitrogenous bases, but the latter includes uracil instead of thymine, which is found in deoxyribonucleotides.
Deoxyribonucleotides are primarily involved in long-term genetic storage, whereas ribonucleotides are more versatile, participating in processes like protein synthesis, gene expression, and as energy carriers.

Any nucleotide containing deoxyribose.


Any nucleotide having ribose as its sugar


An organic molecule consisting of a hereocyclic base attached to the 1-carbon of a deoxyribose ring, with a phosphate group esterified at the 5 position of the deoxyribose. Deoxyribonuceotides are the monomer units which make up deoxyribonucleic acid, the molecule carrying the hereditary information in most organisms. The most common forms of deoxyribonuceotide are thymidine-5´-phosphate (abbreviated TMP), deoxyadenosine-5´-phosphate (abbreviated dAMP), deoxyguanosine-5´-phosphate (abbreviated dGMP), and deoxycytidine-5´-phosphate (abbreviated dCMP).
