Abstract
Extrachromosomal DNA of heterogeneous size has been isolated from bursal lymphocytes and splenocytes of five week old chickens, and from splenocytes of mice. This DNA contains covalently closed circles, open circles, and open circles with tails. Open circular molecules with and without tails are more frequent than covalently closed species, and the total number of small circular DNA molecules per cell is in the range of 100-200 copies.
