• "A variety of chemicals may be used to selectively kill cells that are in the process of dividing. The compound 5-fluorouracil, for example...is mistaken by the cancer cell for the nucleotide base uracil. Once incorporated into the DNA of the cancer cell, 5-fluorouracil's non-nucleotide structure interferes with the normal DNA workings, and the cell dies." 1
