In eastern New England, high concentrations (greater than 10 microg/L) of arsenic occur in groundwater. Privately supplied drinking water from bedrock aquifers often has arsenic concentrations at levels of concern to human health, whereas drinking water from unconsolidated aquifers is least affected by arsenic contamination. Water from wells in(More)
In Escherichia coli, DnaK is essential for the replication of bacteriophage lambda DNA; this in vivo activity provides the basis of a screen for mutations affecting DnaK function. Mn PCR was used to introduce mutations into residues 405-468 of the C-terminal polypeptide-binding domain of DnaK. These mutant proteins were screened for the ability to propagate(More)
The iso-1-cytochrome c gene of yeast has been identified and cloned using a synthetic oligodeoxynucleotide as a hybridization probe. The oligomer d[pT-T-A-G-C-A-G-A-A--C-C-G-G] is complementary to a region near the N terminal coding region of the yeast cyc 1 gene. Of several yeast Eco RI fragments which hybridize to this probe, one is changed in size by a G(More)
