This prevents the conversion of dUMP to 5-Thymidylic acid (dTMP) which is further converted to dTTP, an important precursor for DNA synthesis. DNA synthesis cannot occur as thymidine 5'-triphosphate isn't being produced. This causes the cell to die as it cannot undergo replication, proliferation or differentiation. Fluorouracil is converted to 5-Fluorouridine triphosphate through a series of phosphorylation steps. 5-Fluorouridine triphosphate is incorporated into RNA in place of uracil creating fraudulent RNA that cannot synthesize the correct proteins. Nucleus Cytosol Extracellular Space 5-Fluorouridine triphosphate prevents uridine triphosphate (UTP) from being incorporated in RNA. Fluorouracil is also converted into 5-fluorodeoxyuridine triphosphate through phosphorylation and reduction. 5-Fluorodeoxyuridine triphosphate can be incorporated into DNA synthesis and replication creating fraudulent DNA. This causes the cell to die as it cannot synthesize DNA peroperly.
