Forensic DNA Profiling, Part 3 

Sir...You are a great teacher....thank you very much for sharing this on the you tube. I am really enlightened.

Thank you so much for your series on this! It really helped me for my grade 11 biology project! Loved it!

Great job on all three parts. Thank you.

Even though the gel electrophoresis results are not as precise one would still be able to rule out a suspect based on a large difference in size between a sample found at a crime scene and a known suspect’s sample. And then you would probably check more sites than just DS180. Im guessing the chip can then be used if samples look like they somewhat match but to really confirm.

Why were we dividing by 16 and subtracting by 147 numbers only?

So let me see if I get this right. You did the extraction, PCR, run the gelelectrophoresis and then take the bands from the gel and run that on the chip?

Thank you very much. good.

thank youuuuuu so musch
