| Plate Conditions | LB no Ampicillin plate | LB with Ampicillin plate |
| Both gfp transformed and untransformed bacteria in normal light | none glow more colonies |
none glow less colonies |
| Both gfp transformed and untransformed bacteria in UV light | some glow/some don't more colonies |
all glow less colonies |
On the Ampicillin containing pate, growth will be limited. Glow will only occur when plasmid carrying GFP is present and since the same plasmid also carries the Ampicillin resistance gene, only those colonies that have the plasmid will grow on Ampicillin containing media.

Multiple Choice, Please answer all 4 What is the purpose of the neutralization solution when purifying plasmid DNA? precipitates plasmid DNA lyses the cells contains a detergent precipitates chromosomal DNA and proteins Why does the DNA bind to the purification resin? the resin is negatively charged the resin is hydrophobic the resin is positively charged the resin is neutral Why did you get colonies on plate A but not on B in the transformation, even though both plates had ampicillin?...

.1)a) Why was it important that the –pGLO bacteria were found growing on the LB plate? Why would their absence create problems in interpreting our results? b) What two conclusions (one per plate) should you draw from the observation that –pGLO bacteria did not grow on the LB/amp plate, but that some +pGLO bacteria did? c). Why did we observe bacteria colonies that glowed under UV light when we inoculated +pGLO bacteria on an LB/amp/ara plate, but not when we...

1. On which plate(s) would you expect to find bacteria most like the E. coli on the source plate? Explain. 2. On which plate(s) would you find only genetically transformed bacterial cells? Why? 3. What is the purpose of the control plates? Explain the difference between the controls and why each one is necessary. 4. Why would one compare the -DNA/+Amp and DNA/+Amp plates?

Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change. In either type of situation, when business owners know the law, they can better protect themselves and sometimes even avoid the problems completely. This chapter...
