is part of part of integrated transgene A transgene that has been integrated into a chrromosome in the host genome. An integrated transgene differs from a transgenic insertion in that a transgenic insertion may contain single transgene, a partial transgene that needs endognous sequences from the host genome to become functional (e.g. an enhancer trap), or multiple transgenes (i.e. be polycistronic). Fiurthermore, the transgenic insertion may contain sequences in addition to its transgene(s - e.g. sequences flanking the transgene reqired for integration or replicaiton/maintenance in the host genome. The term 'integrated transgene' covers individual transgenes that were delivered in whole or in part by a transgenic insertion. An 'integrated transgene' differs from its parent 'transgene' in that transgenes can include genes introduced into a cell/organism on an extra-chromosomal plasmid that is never integrated into the host genome. transgene transgenic_insertion
