<P> A large number of other plasmids based on pBR322 have since been constructed specifically designed for a wide variety of purposes . Examples include the pUC series of plasmids . Most expression vectors for extrachromosomal protein expression and shuttle vectors contain the pBR322 origin of replication, and fragments of pBR322 are very popular in the construction of intraspecies shuttle or binary vectors and vectors for targeted integration and excision of DNA from chromosome . </P> <P> The sequence in pBR322 is </P> <Table> <Tr> <Th> pBR322 1 ttctcatgtt
