Plasmids 101: Screens vs. Selections

Selections. Selections differ from screens in that only survivable manipulations are assessed, rather than all manipulation events. To put it another way, only cells or organisms with the desired phenotype will survive and be assayed at the end of the selection process. Non-functional traits will be automatically eliminated, unlike in screens.Web
