What are the differences between phasmid,cosmids,phages,and plasmids.

Hope this brief explanation helps.

Phasmid are hybrid phage/plasmid formed by integration of plasmid containing the att site,and lambda phage,mediated by phage integrase site-specific recombination.

Phages or bacteriophages are viruses that infect bacteria

Cosmids are a type of bacteriophage lambda vector.Often used for construction of genomic libraries,because of their ability to carry relatively long pieces of DNA insert,compared with plasmids.

Plasmid or episomes are a small,independently-replicating,piece of cytoplasmic DNA that can be transferred from one organism to another.
