Police discover a badly decomposed body buried in an area where a man disappeared some years before. the case was never solved, nor was the victim´s body ever recovered. as the lead investigator, you suspect that the newly discovered body is that of the victim. what is your main challenge in using dna typing to determine whether your suspicion is correct? how would you go about using dna technology to test your theory? explain, please.

The main challenge is the poor quality of samples.

Explanation:

The decomposed body would be a bad source of genetic material because every cell on that buried body is at high risk of being decomposed, therefore every genetic material on that body would be as well at risk of being preserved. Given this scenario, there is a low chance that a cell could be used as a sample for different analysis. The main purpose to preserve such material is to be able to compare to other relatives of the body and to determine who really is that body.
