I have always wondered how DNA was process and thought the lab provided a much more down to earth explanation than I originally thought before completing the lab. Another thing that I enjoyed is that fact that the page provided instructions to build your own electrophoresis chamber and try it out at home with food coloring. It is unique how all of the components included react to the negative and positive electrical charge to separate the small and large strands of DNA to determine a profile considering only 0.1 % is unique to each individual except for identical twins. I also found it interesting that today, DNA analysis only requires a small portion that can be obtained off of something as simple as a cigarette butt compared to old methods requiring a much larger portion to be collected. In addition, another factor that made me feel more comfortable about DNA collection is the fact that DNA samples are divided to reduce error and is used to investigate and narrow down suspects with similar DNA among blood…show more content… In the winter if 1981, a young woman was found beaten, raped and murdered in Chichester, Pennsylvania. Nicholas Yarris became the prime suspect and convicted of murder, rape and abduction in 1982, serving 21 years on death row before he was exonerated in 2003 (Innocents Project, 2016). Serological testing performed on the rape kit at the time proved of no value in excluding Yarris of the crime (Innocents Project, 2016). According to the Innocents Project (2016), serology was used before DNA testing as a way to determine the blood type in comparison with the demographic percentage who share the same blood type. Apparently, this can be misleading and misconstrued in court when presenting statistical data among the population demographics. Also, since the blood source of the victim can be mixed with that of the suspect it can make it impossible to determine the blood type of suspect (para,
