If I transform an ade- (adenine minus) ura- (uracil minus) E. coli strain with wild type E. coli chromosomal DNA. How should I select for ade+ transformants? Spread the transformation solution on a minimal medium + adenine Spread the transformation solution on a minimal medium + uracil Spread the transformation solution on a minimal medium + streptomycin Spread the transformation solution on a minimal medium + adenine + uracil
