During electrophoresis, DNA moves towards ——— electrode.

In a transformation experiment, the non-transformed cells plated on LB+Ampicillin plate showed growth.  What would this indicate?

In the transformation experiment performed, the GFP gene confers resistance to the antibiotic Ampicillin.

In the following picture, X represents which enzyme?

During transformation of bacteria with pGFP, any bacteria that have not taken up the pGFP plasmid will not grow on which of the following plates?  

You conduct an ELISA sample to test the presence of antibodies in a patient sample.  After conducting the entire experiment, you suddenly realize that you did not add any substrate (antigen) to the wells in the initial step.  Under such circumstances, the development of a colored reaction in the patient sample (positive result) would indicate a ——-

Cells that have NOT undergone transformation with pGFP should be killed after plating  on LB-AMP.  

In the following figure, the 1:32 dilution of the sample will have less antibodies than the 1:2 dilution (assuming that the dilutions are done correctly)

In a transformation experiment, nutrient Agar plates containing the antibiotic Ampicillin were used in the experiment for what purpose?

The following gel shows the results of a crime scene investigation.  Lane 1 shows a DNA sample that was obtained from the scene of a crime (there was evidence of the criminal cutting himself, so it’s the criminal’s blood sample that produced the DNA bands in lane 1). Lanes 2-7 shows a DNA sample from six potential suspects held in connection with the crime.  Which suspect (#2 through #7) is most likely to have committed the crime?
