Highly purified chicken progesterone receptor (cPR) is shown to stimulate RNA synthesis directly in an in vitro transcription assay. Stimulation of transcription by cPR requires the presence of progesterone response elements (PREs) in the template and can be specifically inhibited by addition of competitor oligonucleotides containing PREs. Binding of(More)
Nucleosomes were treated with increasing concentrations of exonuclease III (Exo III) from E. coli. At low levels of Exo III, the heterogeneous distribution of monomers (with associated DNA fragments ranging in size between 140 and 170 bp) is "trimmed" down to a discrete core of 140 bp. The "trimming" of monomers to 140 bp results from a 3' exonucleolytic(More)
We present the first measurement of the D ‫1ء‬ width using 9͞fb of e 1 e 2 data collected near the Y͑4S͒ resonance by the CLEO II.V detector. Our method uses advanced tracking techniques and a reconstruction method that takes advantage of the small vertical size of the Cornell Electron-positron Storage Ring beam spot to measure the energy release(More)
Using (9.32, 5.88) million Çð2S; 3SÞ decays taken with the CLEO III detector, we obtain five product branching fractions for the exclusive processes Çð2SÞ ! b0;1;2 ð1PÞ ! Çð1SÞ and Çð3SÞ ! b1;2 ð1PÞ ! Çð1SÞ. We observe the transition b0 ð1PÞ ! Çð1SÞ for the first time. Using the known branching fractions for B½Çð2SÞ ! bJ ð1Pފ, we extract values for B½ bJ(More)
