One tautomer behaves like T and the other behaves like … Figure 11. Previous question Next question. If skin irritation persists, call a physician. The potential energy surfaces of stacked base pairs consisting of cytosine (C), thymine (T), uracil (U) and the mutagenic thymine analogue 5-bromouracil (BrU) have been searched to obtain all possible minima. 2AP base pairs with C, converting an AT base pair to a GC base pair after several rounds of replication. Here, the deactivation of 5-bromouracil after ultraviolet irradiation is investigated in the singlet and triplet manifold by accurate quantum chemistry One of the most common base analogs is 5-bromouracil (5BU), the abnormal base found in the mutagenic nucleotide analog BrdU.4) with 5-nitrouracil (pK a 5.

It is a member of pyrimidines and a … The substituted base 5-bromouracil (BU) is an analogue of thymine inasmuch as the bromine atom has about the same van der Waals radius as the methyl group of … An analog of adenine, 2-aminopurine, also causes mutations in a similar way since it can pair with either T or C.: 957 … 5-Bromouracil is a nucleobase analogue that can replace thymine in DNA strands and acts as a strong radiosensitizer, with potential applications in molecular biology and cancer therapy. An analog of adenine, 2-aminopurine, also causes mutations in a similar way since it can pair with either T or C. When a nucleotide containing 5-bromouracil is incorporated into the DNA, it is most likely to pair with adenine; however, it can spontaneously shift into another isomer which pairs with a different nucleobase, guanine. It is used mainly as an experimental mutagen, but its deoxyriboside derivative (5-bromo-2-deoxy-uridine) is used to treat neoplasms.6) or 5-bromouracil (p K a 8. Used mainly as an experimental mutagen. It has been suggested that bromouracil is mutagenic because it has a greater ability than thymine to mispair with guanine (1).
