Cosmids and gene cloning

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 #geneMapping #geneLibrary #genetics #plasmid #DNA #Phage
