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)
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)
We consider the three-dimensional incompressible Navier-Stokes equations in a domain of the form 0 (0;). We assume no-slip boundary conditions on @ 0 (0;), periodic conditions on 0 f0;g, and show that with certain assumptions on the initial condition and forcing function a strong solution exists for all time. Physically, these boundary conditions model uid(More)
Continuing our studies of radiative Υ decays, we report on a search for Υ → γη and Υ → γf J (2220) in 61.3 pb −1 of e + e − data taken with the CLEO II detector at the Cornell Electron Storage Ring. For the γη search the three decays of the η meson to π + π − π 0 , π 0 π 0 π 0 , and γγ were investigated. We found no candidate events in the (3π) 0 modes and(More)
