Materials for each group of students: Use the wooden stirrer to start poking the cloudy stuff in the alcohol layer. Three examples of why scientists might need to indentify DNA are for genetic testing, body identification, and analysis of forensic evidence. Throughout the entire experiment there were many possible ways that the ending result of the appearance of the DNA could have differed.
