Size and shape of mitochondrial DNA molecules of Schizosaccharomyces pombe were analyzed by electron microscopy. Besides numerous linear molecules, circular molecules ranging from 0.83 micron to 12.81 micron were found. Depending on the method of preparation, both closed and open circular molecules

A population of small covalently closed non-mitochondrial circular DNA molecules was isolated from the petite-negative yeast Schizosaccharomyces pombe. The mean length of these molecules, possessing the same density as nuclear DNA (1.695 g/cm3) is 1.95 +/- 0.18 micrometer. The presence of these mini
