Cloned synthetic lac operator DNA is biologically active
Abstract
A chemically synthesised duplex DNA fragment containing the sequence of the lac operator was cloned in E. coli using the vehicle pMB9. Clones containing lac-pMB9 hybrid DNA produced beta-galactosidase constitutively and the hybrid DNA bound the lac repressor specifically.
