A fragment of the 16S RNA of Thermus thermophilus corresponding to the central domain (nucleotides 547-895) has been prepared by transcription in vitro. Incubation of this fragment with the total 30S ribosomal proteins has resulted in the formation of a compact 12S ribonucleoprotein particle. This particle contained five T. thermophilus proteins corresponding to Escherichia coli ribosomal prote...

Introduction This Auxiliary Material contains detailed discussions of our study sites and of each coral head analyzed. We methodically describe the Bunon sites (Text S1 and Figures S1–S12) and Pulau Penyu site (Text S2 and Figures S13–S18), and we explain the construction of relative sea-level histories, considering multiple scenarios where data are ambiguous. Supplementary tables provide detai...

The Bacillus subtilis genome comprises two paralogous single-stranded DNA binding protein (SSB) genes, ssb and ywpH, which show distinct expression patterns. The main ssb gene is strongly expressed during exponential growth and is coregulated with genes encoding the ribosomal proteins S6 and S18. The gene organization rpsF-ssb-rpsR as observed in B. subtilis is found in many gram-positive as we...

Microfabricated silicon gratings provide unique test procedures for instruments in neutron scattering and the interpretation of experimental data. Ultra-Small Angle Neutron Scattering (USANS) is currently becoming an effective technique for the analysis of structures in the micrometer range. A series of one-dimensional silicon gratings was fabricated using a highly anisotropic ion etching techn...
