Our goal was to assess the microtubule translocating ability of individual ATPase subunits of outer arm dynein. Solubilized outer arm dynein from sea urchin sperm (Stronglocentrotus purpuratus) was dissociated into subunits by low ionic strength buffer and fractionated by zonal centrifugation. Fractions were assessed by an in vitro functional assay wherein microtubules move across a glass surfa...

The length of double-stranded coliphage lambda DNA, as determined by electron microscopy using the benzyldimethylalkyl ammonium chloride technique, depends on the mode of dehydration. The freeze-dried DNA form is the longest (16.5 micron), whereas dehydration in methanol (15.9 micron) or in ethanol (three forms: 15.2 micron, 13.9 micron, and 12.4 micron) results in progressively shorter molecul...

Springer, Victor G. Pacific Plate Biogeography, with Special Reference to Shorefishes. Smithsonian Contributions to Zoology, number 367, 182 pages, 65 figures, 5 tables, 1982.—It is the thesis of this study that the Pacific lithospheric plate (Pacific Plate) forms a major subunit of the Indo-Pacific biogeographic region. This thesis is defended on two primary grounds: the sharp decrease in numb...

Female SENCAR mice were treated with aqueous solutions of hypochlorous acid (HOCl), sodium hypochlorite (NaOCl), chlorine dioxide (ClO2), and monochloramine (NH2Cl) by whole body exposure (except head) for a 10-min period for 4 days in the first experiment and for 1 day (except NH2Cl) in the second experiment. Animals were sacrificed the day following the last treatment (experiment 1) or on day...
