A NEW SCREENING METHOD FOR MUTAGENS:λ DNA REPACKAGE IN VITRO.——Ⅰ.PRELIMINARY STUDY ON THE MUTAGENICITY OF 11 CHEMICALS

摘要

λ DNA repackage in vitro is an important method ingene-engineering research,this method was used to screenmutagens in our present study.11 chemicals were tested todemonstrate the reliability of the method.λ DNA was treatedwith chemical mutagens directly,then added to
