Abstract excerpt
The yeast 2 microns plasmid is found in the nucleus of almost all Saccharomyces cerevisiae strains. Its replication is very similar to that of chromosomal DNA. Although the plasmid does not encode essential genes it is stably maintained in the yeast population and exhibits only a small, though detectable, loss rate. This stability is achieved by a plasmid-encoded copy-number control system which ensures constant...
