We have mapped transcription termination sites for RNA polymerase I in the yeast Saccharomyces cerevisiae. S1 nuclease mapping shows that the primary terminator is the Reb1p terminator located at +93 downstream of the 3′ end of 25S rRNA. Reverse tr

We identify Rpa12p of RNA polymerase I (Pol I) as a termination factor. Combined analyses using transcription run-on, electron microscopy-visualized chromatin spreading and RT-PCR have been applied to the rRNA-encoding genes of Saccharomyces cerevisi

Male Swiss Webster mice were fed the organophosphate pesticide, leptophos, in feed at concentrations of 0, 10, 100, and 500 ppm for 12 weeks. Signs of organophosphate poisoning were moderate to severe inhibition of serum cholinesterase and decreased

Mice were exposed to 0, 13, or 1,300 ppm lead in drinking water for 18 months. The immunological assays examined were mitogen (lipopolysaccharide E. coli, concanavalin A, and phytohemagglutinin‐P) stimulation of lymphocytes; erythrocyte‐antibody

The DNA regions required for accurate initiation by RNA polymerase 1 on the ribosomal RNA genes of Xenopus laevis consist of at least two domains within a 150 bp segment adjoining the initiation site. A region of only 13 nucleotides (from -7 to +6) a

We have compared the DNA sequences of several different examples of the duplicated polymerase I promoters that are found in rDNA spacers of Xenopus laevis. Although different spacers exhibit different amounts of transcription in vivo, this does not s

From information presented in this volume and elsewhere, it is now clear that major control of eukaryotic gene expression is exerted at the transcriptional level, apparently largely at the initiation step. Consequently, much interest is being devoted

We have mimicked the phenomena of nucleolar dominance by injecting cloned ribosomal genes from X. laevis and X. borealis into oocytes from either species and into embryos. The results of these experiments suggest that the dominance of the laevis ribo

CBA mice were exposed to lead acetate or cadmium chloride in drinking water for 10 weeks. Selected groups of these animals were also injected with Bacillus Calmette-Guerin (BCG) during exposure to the metals. The ability of mitogens concanavalin A (C

We have assayed a series of linker scanner mutants which cover the Xenopus laevis ribosomal gene promoter at approximately ten base pair intervals. All of these mutations adversely affect promoter activity with the exception of one mutation which sti
