Although the E. coli strain used in these experiments has been rendered non-pathogenic, it is important to teach the students good sterile technique and safe disposal of bacteria. Sizes of unknown DNA fragments can be determined by seeing how far in the gel they move. The transformation effectiveness was then determined by analyzing the amount of resulted colonies created. This new genetic information often provides the organism with a new trait which is identifiable after transformation. a. The transformation of bacterial cells is a useful experiment to help develop an understanding of transformation by plasmid DNA. All of the samples ended up moving in the opposite direction you expected. Why do you think it would be necessary to use PCR to amplify the region of DNA you wish to analyze?
