Organic base found in RNA. Uracil pairs with adenine and is denoted by the letter ‘U’.

Use in clinical context

The pairing of bases allows RNA to be translated into polypeptides. In RNA uracil takes the place of thymine in DNA. The order of bases in a gene determines the order of amino acids in a protein. Changes to the bases can result in changes to the amino acids and the resulting protein function.
