NA fingerprinting (p.459) What process makes copies of a specific DNA sequence? PCR How much DNA is required at the start for this process to work at amplifying (copying) this target sequence? Less than one part in a million Why would this process be useful in analyzing the DNA in mummified human brains? Because maybe only one out of a million were preserved to analyze. How can the repeat DNA sequences in a human DNA sample be detected? By the repeats of the DNA in a location. How do organisms differ with respect to the repeats? If two DNA patterns match, then they are most likely from the same thing. Which process can separate amplified (copied) DNA based on its size? Gel Electrophoresis What type of pattern is produced? A pattern of distinctive bands As the number of repeats increases in a human DNA segment, what will happen to the size of that segment. It will be bigger When comparing band patterns to identify the human individual that was the source of the DNA is called? DNA fingerprinting. Why do individuals have unique DNA fingerprints? Because every person has a unique DNA pattern Describe FOUR of the uses of DNA fingerprinting. DNA can match a virus or mutated gene, it is known that it is present. DNA from a single sperm can identify a rape suspect. It can be used to identify remains of bodies, and can also be used to match blood to a crime scene. DNA Fingerprinting and the Criminal Justice System (p.464) Would you be willing to provide your DNA for a national DNA databank? Yes because I don’t plan on killing anyone but if I died or something and my body was found I would be able to be identified. Why or Why not? What type of privacy restrictions would you want on your DNA, if in a databank? That they could only be observed and used under emergency circumstances with permission from me or a family member. If not everyone, do you think convicted felons, at least, should be required to provide DNA for a databank? Why or why not? Should all defendants have access to DNA fingerprinting to prove they didn't do a crime? Why or Why not? Yes, because it is always effective and if someone is innocent and willing to prove it with DNA then it shouldn’t be denied. Should this include those already convicted of crimes who want to reopen their cases using new DNA evidence? Yes, they weren’t given equal opportunity as people convicted now a days, and so I think they should.
