Recombinant DNA and Gene Cloning
... Some plasmids are copied at about the same rate as the chromosome, so a single cell is apt to have only a single copy of the plasmid. Other plasmids are copied at a high rate and a single cell may have 50 or more of them. Genes on plasmids with high numbers of copies are usually expressed at high le ...
