Deoxyribonucleotide and ribonucleotide are different forms of nucleotides found in either DNA or RNA. Deoxyribonucleotide is the monomer in DNA. Deoxyribonucleotide has three components which are: a deoxyribose sugar, a nitrogenous base, and a phosphate group. Ribonucleotide reductase is the enzyme that causes the reduction of ribonucleotide to deoxyribonucleotide.

The hydroxyl group present at the second carbon in the ribose ring is replaced with a hydrogen atom to form deoxyribose. Without this enzyme, deoxyribose cannot be made. Ribonucleotide is the monomer present in RNA. The sugar component in RNA is ribose, unlike DNA that has deoxyribose. Ribonucleotide also has a nitrogenous base and a phosphate group with ribose sugar.

The main distinctness between ribonucleotide and deoxyribonucleotide is that ribonucleotide is the forerunner molecule of RNA while the deoxyribonucleotide is the harbinger molecule of DNA. The ribonucleotide molecule is made up of a ribose sugar while deoxyribonucleotide molecule is made up of a deoxyribose sugar. Both molecules are two types of precursor molecules of nucleic acids, and both are made up a pentose sugar, nitrogenous base, and phosphate groups.
