The ancient remains of several human bodies have been discovered and legally need to be returned to the tribe that contains the closest descendents. You have been called as a witness in the resulting legal case to give your opinion. The jury is confused about the analysis you have done. Could you please explain it to them again?Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Not all terms will be used. gel electrophoresis Southern blot restriction map DNA extraction DNA fingerprint restriction enzymes chromosome walking VNTRs polymerase chain reaction hybridization to a probe compared the sample to modern DNA samples controls 1. After obtaining the samples (preserved bone and muscle fragments l conducted a 2. Because suspected the ancient DNA would be degraded, l pretreated it with random primers and the Klenow fragment (a procedure found to help repair damage and aid amplification) and amplified the DNA using 3. To make sure that the DNAlanalyzed was indeed from the ancient sample, during these procedures, l used both positive and negative 4. Following amplification l used to cut out the DNA fragments with the genes l wanted to study. 5. Then used to separate the DNA fragments. 6. l performed a in which I transferred the DNA onto a filter and then incubated the filter with a radiolabeled DNA sequence complementary to the gene l was interested in 7. This final step with the radiolabeled DNA sequence is called I can repeat this step for multiple genes 8. l used several highly variable loci to create a specific 9. Finally, I in order to determine the group most closely related to the individual who the sample was taken from.
