PREDICT PCR RESULTS
Name:_Date:
Class Period:
Hypothesis:
Do you expect this sample to have the 35S promoter indicative of the Roundup Ready
Gene and why?
If this sample does as you predict will is show a PCR product?
Draw an image of the gel below, assume that the size of the band is at the 100bp mark. Lane 1 is for positive control (a sample that is known to be GM), lane 2 is for negative control (a sample that is known to not be GM), lane 3 is for your sample.
