Hypothetical criminal investigation

Write a one-page affidavit identifying the killer for the court. To justify your identification, note where the DNA samples came from, describe how PCR analysis works (the components, their roles, and the purpose of each step in the reactions), and explain how you came to your conclusion.The Affidavit does not have to be an official formatted document. It can be in the form of a paper as long as it answers all the required questions!

Purpose:

To explore the science and methodology of the polymerase chain reaction (PCR) and its applications in forensic science

Objectives:

Research the concepts and methodologies of PCR (see videos in this folder)

Review evidence from a hypothetical criminal investigation and examine PCR profiles of several potential suspects

Compose an affidavit identifying the suspect and the supporting PCR evidence

What you will do:

Research the concepts and methodologies of PCR

Review evidence from a hypothetical criminal investigation and examine PCR profiles of several potential suspects

Compose an affidavit identifying the suspect and the supporting PCR evidence

The steps to follow:

Research the technique and science of PCR, using the suggested videos, and complete DNA Analysis: PCR (file can be found above).

Using PCR Profiles: Who Killed Clotilda? (file can be found above), read background information on the crime. Compare the PCR profiles derived from crime scene evidence to those of the victim and the suspects.

Write a one-page affidavit, according to the directions in PCR Profiles: Who Killed Clotilda?. Justify your identification by discussing the validity of PCR analysis in criminal cases.

Answer preview

The DNA of human beings is 99.9% the same, whereas the other 0.1% differs in the variable number of tandem repeats (VNTRs). This identifies suspects in crime scenes where the evidence at the scene is compared to the suspect’s DNA using a method called DNA fingerprinting (Parson, 2018). Finally, on the validity of PCR analysis in criminal cases, the technology can come in handy in identifying and distinguishing one person from several
