Uracil vs. Uridine: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Uracil is a nitrogenous base found in RNA, while uridine is a nucleoside comprising uracil attached to a ribose sugar.
Key Differences
Uracil is one of the four nitrogenous bases used in the RNA molecule, playing a crucial role in the storage and transfer of genetic information. Uridine, on the other hand, is a nucleoside formed when uracil is attached to a ribose sugar, making it a building block of RNA.

In RNA, uracil pairs with adenine, replacing thymine found in DNA. Uridine is involved in various biochemical processes and is crucial for the synthesis of RNA, where it incorporates uracil into the RNA strand.

Uracil is a pyrimidine base and has a simple structure with a single ring. Uridine, however, is more complex, consisting of the uracil base linked to a pentose (ribose) sugar, forming a larger molecule.
