PHENOTYPIC AND GENOTYPIC CHANGES IN BACTERIA
Students use a rapid method to render the bacterium Escherichia coli "competent" in order to uptake plasmid DNA. They also have growth on the plain LB plates by the untransformed cells (which serve as controls). Students perform a cell...
Curated OER
Phenotypic and Genotypic Changes in Bacteria
Students investigate a rapid method to render the bacterium Escherichia coli "competent" to uptake plasmid DNA. They demonstrate the phenotypic changes associated with transformation. They perform a cell resuspension from the...
