Before diving into the images, we need a baseline definition. A cosmid is a hybrid vector that combines the features of a (circular DNA, antibiotic resistance, origin of replication) with the cos site of a bacteriophage (lambda phage). This unique hybrid allows cosmids to carry large DNA inserts—typically 35 to 45 kilobases (kb)—much larger than traditional plasmids (which max out around 10 kb).
Efficiently packaged into viral particles for high-efficiency infection of host cells. Disadvantage
