Abstract excerpt
A 4.05-kb DNA fragment containing the ADE2 gene from Schwanniomyces occidentalis was cloned into the pUC19 vector. When an ade2 strain of Sc. occidentalis was transformed with this plasmid, pADE-2 was found to integrate into the host chromosome and was also present in a variety of extrachromosomal species. These extrachromosomal elements were present in multiple copies, varied in molecular mass and were composed...
