(n) Genetics A hybrid vector that has been spliced with plasmid DNA for cloning huge genes or gene fragments.
(n) a kind of plasmid (often utilized as a cloning vector) constructed because of the insertion of cos sequences, that are DNA sequences of this lambda phage.
(n) (genetics) a large vector which produced from a bacteriophage and used to clone genes or gene fragments
cosmid in Medical Dictionary
DNA from a bacterial virus into that is spliced a tiny fragment of a genome to be amplified and sequenced. A cosmid is an artificially built structure. It is used in cloning (copying) items of DNA. by SaulReport definition
(On a technical level, a cosmid contains the cos gene of phage lambda and that can be packed in a lambda phage particle for disease into E. coli, allowing cloning of bigger DNA fragments that may be introduced into microbial hosts in plasmid vectors). by Elmira TorbertReport definition
