DNA FINGERPRINTING
1.In your opinion, what role (if any) did newspaper stories and editorials have in the outcome of the original trial of Dr. Sam Sheppard?
What they did was egg the trial on and they always had something to say. When they believed he was free the paper would put something else in their to make him look guilty and that the people thought that also.
2.What is the function of the restriction enzymes in DNA fingerprinting?
The enzymes work as scissors and, cutting the long DNA molecules at different locations.
3.What is the function of the agarose gel electrophoresis step?
It acts as a molecular strainer, allowing smaller pieces of DNA to move through more easily than larger pieces.
4.Why is a nylon membrane used to blot the DNA?
The gel is difficult to work with, the DNA is transferred to a nylon membrane. The DNA was sucked up into the membrane as a liquid traveled up from the gel toward an absorbent material that was placed over the membrane.
5.What does a dark spot on the X-ray film indicate?
Exposes corresponding areas on the X-ray film.
MS. HONEY SWEET WAS THE RIGHT MATCH!!!
6.What evidence was initially used to convict Cotton?
A photo identification was made by one of the victims.
A police lineup identification was made by one of the victims.
A flashlight in Cotton's home resembled the one used by the assailant.
Rubber from Cotton's tennis shoe was consistent with rubber found at one of the crime scenes
7.What did the DNA evidence show?
That Cotton was not a match and they found a victim that was a match and confessed.
8.How could DNA fingerprinting be used to prevent a false conviction if a case like this was being tried today?
Because everybody has their own fingerprint so they can match that person to the fingerprint and find the actual criminal.
9.What percentage of convicts are unjustly convicted of sexual assault cases, according to Neufeld and Scheck?
25%
10. The O.J. Simpson trial was one of the most visible trials that attempted to use DNA evidence. In the end, the DNA evidence was not satisfying to the jury, who acquitted Simpson. What do Neufeld and Scheck believe about the impact of the O.J. Simpson trial on the use of DNA evidence?
They believe the impact was to be more cautious because in cases like this you have to use technology wisely and cautiously.
