- Plasmids: A common type of cloning vector, plasmids are circular DNA molecules found in bacteria. An example is PBR322, which contains an origin of replication and selectable markers for antibiotic resistance. - Bacterial Artificial Chromosomes (BACs): These are larger cloning vectors derived from...
