Uracil is widely used in molecular biology genetics and biochemistry research and it is also used in pharmaceutical and microbiological studies involving RNA metabolism and nucleic acid analysis.

The purpose of uracil is to pair with adenine during RNA synthesis enabling the storage and transmission of genetic information and supporting protein synthesis.

Uracil is a pyrimidine nitrogenous base that is one of the four bases found in ribonucleic acid (RNA).
