1. Explain the proper collection and packaging methodologies for biological evidence. Why should biological evidence never be packaged in air-tight or non-breathable mediums?
2. What is PCR analysis? Why is this application important particularly for cold cases or cases in which only a small amount of DNA is recovered?
3. What is STR analysis? Why is this an effective method for DNA typing?
Original responses to the Forum questions each week need to be substantial (350 words) and significantly supported by two scholarly references. Students must also use proper spelling, grammar, and sentence structure. The in-text citations and references will be in APA Format.
