Commonly-used types include pUC18 and pBluescript, and often contain artificially-inserted cloning sites and antibiotic resistance genes.  
Commonly-used types include pUC18 and pBluescript, and often contain artificially-inserted cloning sites and antibiotic resistance genes.  Occurring primarily in yeast and bacteria, they are used in recombinant  DNA procedures as intercellular vectors. For ten points, identify this type of autonomously replicating, non-chromosomal, circular DNA.
