Abstract: Method, compositions and microorganisms involving host eukaryotic chromosomal DNA providing autonomous replicating segments (ars) joined to at least one gene capable of expression and replication in a eukaryotic host not naturally joined to the ars. A eukaryotic chromosome is segmented and the segments joined to a gene capable of expression in a yeast and having a phenotypic marker allowing for selection to provide a hybrid DNA molecule. Yeast are transformed with the hybrid DNA molecule and cultured under conditions selecting for the transformants, whereby the hybrid DNA molecules may be isolated providing a source of the autonomous replicating segment. The autonomous replicating segment may then be used in conjunction with one or more genes to transform the host or other eukaryotes to provide for multiple copies of a host gene, an exogenous gene. or for integration or recombination with the host chromosome, as well as expression of the gene(s).

Abstract: In this cylindrical, magnetically-enhanced, sputtering cathode, the magnetic field at the cathode target is generated by applying an electric current through a hollow electrical conductor dis-posed within a tubular target, so that the electric current flow-ing along this conductor induces circular magnetic lines concentrically around its axis. By biasing negatively the tubular target immersed in a low pressure gas, a glow discharge is generated. Electrons, emitted from the target surface are accelerated radially by the electric field, but deviated perpendicularly by the magnetic field. The resulting motion is confined in a spirally-shaped area centered on the conductor axis.
