Analyze and answer:
1.If you see a band in the electrophoresis gel in the sample 1 lane and it is the same size as the band that appears in the lane where the E. coli bacteria control is placed on the gel, what does it mean?
2. On the other hand, if you don't see a band the same size as the positive control on the gel, what does it mean?
3. If you have bands in the negative control (distilled water), what could have happened?
