Physical properties of a plasmid-like DNA from Euglena gracilis.
A small circular extrachromosomal DNA of the flagellate protozoan Euglena gracilis has been characterized as having a contour length of 11.3 kb, with a consistent restriction map. The buoyant density (rho = 1.717) and melting temperature (tm = 89 degrees C) both indicate a base content of 59% G + C. The DNA is found in both wild-type cells and those lacking plastids. The copy number is estimated to be about 1000.
