Problem:When Roger Rabbit was found dead, investigators found hair and blood that didnít belong to him.Who killed Roger Rabbit?

 

Hypothesis:Who do you think killed Roger Rabbit, the blonde male with type B blood, the dark-haired male with type O blood, or the blonde female with type O blood?

 

 

 

Experiment:

Materials:

Blood samples (synthetic) from victim and killer††††††††††††††††††††††††††††

Prepared slides of hair samples

DNA profiles (UPC codes) for each suspect and victim††††††††††††††††

Microscope

ABO blood-typing kit for synthetic blood

†††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††

Procedure:

1.Look at the hair samples for the killer and the victim under the microscopes and record your results in the data table.

2.Using the instructions in the ABO Blood-typing Kit, test the victimís and killerís blood.Record your results in the data table.

3†† After you have determined who the killer is from the hair and blood evidence, compare the DNA profile of that person with the profile of the killer.(Your teacher has that piece of evidence.

 

 

Data:

 

Blood Type

Hair Color

Victim††††††††††††††††

 

 

Killer

 

 

 

Conclusion:

1.†† What information did you learn from the microscope?

 

 

 

2.†† How are the bar codes (in the UPCís) like DNA fingerprinting?

 

 

 

 

3.†† Who killed Roger Rabbit?
