A cosmid is a type of hybrid plasmid that contains a Lambda phage cos sequence. Cosmids` (cos sites + plasmid = cosmids) DNA sequences are originally from the lambda phage. They are often used as a cloning vector in genetic engineering. Cosmids can be used to build genomic libraries. They were first described by Collins and Hohn in 1978. Cosmids ....

Type: Term Pronunciation: koz′mid Definitions: 1. A recombinantly engineered plasmid, a circular DNA containing, in order: a plasmid origin of replication and a drug-resistance marker, the cos (cohesive end) site from bacteriophage λ, and a fragment of eukaryotic DNA to be cloned; cosmids are constructed to permit cloning of fragments of...

Cosmid: DNA from a bacterial virus into which is spliced a small fragment of a genome to be amplified and sequenced. A cosmid is an artificially constructed structure. It is used in cloning (copying) pieces of DNA. (On a technical level, a cosmid contains the cos gene of phage lambda and can be packaged in a lambda phage particle for infection into...
