Evidence is presented for the occurrence of bromouracil-guanine base pairs in product DNA in the G x C----A x T pathway where guanine is present in the DNA template and bromouracil is present as … Aside from its incorporation into deoxyribonucleic acid, 5-bromouracil inhibits thymine utilization, is reversed by thymidine competitively, and inhibits uracil formation or utilization.1) is a change in the nucleotide sequence of a short region of a genome ( Figure 14. It is used mainly as an experimental mutagen, but its deoxyriboside derivative (5-bromo-2-deoxy-uridine) is used to treat neoplasms. Ultraviolet light causes thymine dimers.
