WebA bacterial artificial chromosome ( BAC) is a DNA construct, based on a functional fertility plasmid (or F-plasmid ), used for transforming and cloning in bacteria, usually E. coli. [1] [2] [3] F-plasmids play a crucial role because they contain partition genes that promote the even distribution of plasmids after bacterial cell division. WebCloning vectors are DNA molecules into which foreign DNA can be inserted. Typically, scientists adapt naturally occurring structures that can replicate independent of chromosomal DNA. For example, plasmids are circular, double-stranded DNA molecules (see image …

WebThey 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. [2] Cosmids can contain 37 to 52 (normally 45) kb of DNA, limits based on the normal bacteriophage packaging size. They can replicate as plasmids if they have a suitable origin of ... WebMethod #2: A powerful way. An effective method to simplify screening is to use a positive selection system – a twist on the blue/white system mentioned above. Positive selection vectors conditionally express a lethal gene, such as a restriction enzyme that digests the genomic DNA of the bacterial host.
