Crime Scene Evidence

APBIO-8EKEDT

Below is a DNA fingerprint for a criminal case made using RFLP analysis. From left to right, the wells represent a standard, evidence from crime scene, two similar parts of the genome from John Smith’s blood, and two similar parts of the genome from Jane Jone’s blood.

"Genetics." Sample Final Exam. N.p., n.d. Web. 03 Mar. 2016. http://faculty.rio.edu/lindas/genetics/genstudyguides/gentest5.html.

CSi represents the DNA taken from the crime scene at two locations.

The Std. (standard) lane is used for distance length references.

Which of the following does this RFLP analysis indicate?

A

The evidence is inconclusive.

B

Jane Jone’s DNA was found at the crime scene.

C

John Smith’s DNA was found at the crime scene.

D

Both Jane and John appear to be guilty of the crime.
