Question

Which suspect is the perpetrator of this crime? Explain the results you see in the DNA gel. Why each DNA sample generates two bands in the DNA gel? Explain. I'm just really lost on this, and do not know how to tell which is the suspect :( Thank you!!

Answer 1

The perpetrator must have the same DNA profile as the one found in the crime scene. In this case, the only suspect whose DNA profile matches with the CS DNA profile is suspect C. That is, suspect C has the same genes/DNA fragments that the ones encountered in the Crime Scene.
