Dimethyl sulfate and its hydrolysis product monomethyl sulfate have been found at concentrations as high as 830 parts per million in fly ash and in airborne particulate matter from coal combustion processes. This discovery poses a new environmental problem because

We have measured the effect of the histones in the nucleosome core particle on methylation of purines in nucleosome DNA by dimethyl sulfate. By using 32P terminally labeled nucleosome cores, we have examined the pattern of strand cleavage at methylated

The physical properties of polyaniline (PAn) powder, doped by nucleophilic doping of dimethyl sulfate (DMS), were characterized, as well as its electrochemical behaviors, to investigate the possibility of a power source device adopting the PAn-DMS electrodes. It is shown that

Pre-ribosomal particles undergo numerous structural changes during maturation, but their high complexity and short lifetimes make these changes very difficult to follow in vivo. In consequence, pre-ribosome structure and composition have largely been inferred from purified particles and analyzed in

CK2 phosphorylates the scaffold protein XRCC1, which is required for efficient DNA single-strand break (SSB) repair. Here, we express an XRCC1 protein (XRCC1(ckm)) that cannot be phosphorylated by CK2 in XRCC1 mutated EM9 cells and show that the role of
