    Notes: [Auszug] Cells were grown and diploids were constructed by previously published methods3 using genetically marked parent strains. In every case diploid clones were shown to segregate the appropriate recessive genetic markers. Two- to three-day-old fruiting bodies cultured on water agar in the presence of ...

    Notes: The formation of secondary sori in whorls of Polysphondylium pallidum provides an attractive model system for the study of symmetry breaking during morphogenesis. Tip-specific antibodies that permit detection of very early stages in this patterning process are available. We have found that the patterns of tip-specific antigen expression vary considerably depending on the size, shape, and developmental stage of the whorl. All of these patterns, however, are well explained by patterning models that rely on short-range autocatalysis and long-range inhibition, as exemplified by reaction-diffusion theories. In the context of reaction-diffusion, we discuss the possible effects of initial conditions, boundary conditions, and nonlinearities on the selection of patterns in P. pallidum whorls.

    Sedimentation coefficient of T-even bacteriophage DNA (1966)
    New York : Wiley-Blackwell
    Biopolymers 4 (1966), S. 747-757 
    Details
    ISSN: 0006-3525
    Keywords: Chemistry ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The sedimentation coefficient of T2 phage DNA has been studied by zone centrifugation in sector-shaped preparative centrifuge tubes over a concentration range of 0.02-2.0 μg./ml. DNA. These results have been compared to a similar study in the analytical centrifuge of T4 DNA over the range of 0.50-5.75 μg./ml. DNA. A value for the sedimentation coefficient of 60.7 ± 1.8 S. was obtained by the first method and a value of 61.3 ± 1.5 S. by the second.
