A NEW SCREENING METHOD FOR MUTAGENS:λ DNA REPACKAGE IN VITRO.Ⅱ.THE MOLECULAR MUTATION MECHANISMS OF 8 CHEMICALS MEASURED BY ELECTROPHORESIS.

摘要

In this study 8 chemicals were analysed by electro-phoresis in order to explore their molecular mechanisms ofmutation in λ DNA repackage in vitro.The doseages werechosen according to the dose which can induce significantdifference in numbers of λ clear-plaques in λ DNA
