Acetabularia Chloroplast DNA: Electron Microscopic Visualization

Beverley R. Green 1 and Hugh Burton 1

1 Department of Botany, University of British Columbia, Vancouver 8

Isolated chloroplasts of Acetabularia mediterranea, lysed by osmotic shock in a protein monolayer, released large amounts of supercoiled DNA. In some cases, the DNA radiated in large loops from centers of organization. The amount of DNA per chloroplast may be similar to that of a bacterium.
