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?

A fragment of DNA that is 3000 bases long will run farther than a 1000-bp long fragment during gel electrophoresis.

During a PCR reaction in progress, the PCR machine malfunctions and therefore cannot not maintain a temperature of 95oC.  Name the step of the PCR process that will be directly affected by this problem.

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.  Arrange the bands labeled A, B, C, D from largest to smallest.

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