1) A forensic scientist is required to collect blood samples from the crime scene and analyze it to help the investigators understand who participated to the murder. i) As a first step, the scientist needs to extract DNA. Indicate why red blood cells are not a good target for the analysis, and list at least two chemicals/compounds that are required to extract the DNA, explaining why they are used. ii) The sample has been collected in a small amount, so that (s)he decides to use PCR to analyze it.
