A (6—4) photoproduct of 5-bromouracil
The photoreactions of 5-bromouracil (BrUra) induced by 254 nm radiation have received a significant amount of scrutiny over the years, both when induced in liquid aqueous solution and in the frozen state. The ...

Photoinduced ring opening reactions and subsequent thermal ring closure reactions in the thymine—ammonia system and related systems
The photo-induced ring opening reactions of thymine (Thy) and 1-methylthymine (MeT) with ammonia and with methylamine (MA) at basic pH, and the subsequent ring closure reactions of the resulting adducts, have ...

The cyclobutane dimers of 5-methylcytosine and their deamination products
The photochemical reactions of 5-methylcytosine (m5C), a minor component of mammalian DNA, have been studied at a concentration of 2 mM in frozen 10 mM aqueous NaCl solution at dry ice temperature (194.5 K). For ...

Cross-Linking of Proteins to Nucleic Acids by Ultraviolet Light
Early in the 1960s Smith (1962) and Alexander and Moroson (1962) independently published experimental results indicating that absorption of ultraviolet light could induce cross-linking of protein to DNA in liv...
