Abstract: Plasmids which are in themselves unstably inherited or which have become unstable due to the insertion of a DNA fragment comprising one or more genes not naturally related to the plasmid are stablized by means of a partitioning function exerted by a par region, especially a plasmid R1 par region, inserted into the plasmid on a DNA fragment which may be the length of the wild-type R1 EcoR1-. A fragment, but which is preferably shorter than this fragment, and which may comprise the R1 par region A, the R1 par region B or both these R1 par regions. The stabilization obtained for several different types of plasmid, especially by employing both R1 par regions, approaches the stability level of wild-type plasmids, i.e. they typically have a frequency of loss of less than 5.times.10.sup.31 6 per cell per generation.

Abstract: An improved flexible coaxial cable (24) and method of making same employs an inner conductor (22) having a helically wound dielectric beading (20) wound thereabout in a predetermined pitch dependent on the desired velocity of propogation for the cable (24).
