Why observe samples: - correct answer ✔✔1) identify potential subjects
2) exonerate individuals
3) identify crime and casualty victims
4) establish paternity
5) match organ donors

, Radioactive Phosphorus - correct answer ✔✔used to tag DNA in Hershey and Chase's
experiment
-32 probes are added to the membrane which bond to the precise DNA fragments making them
radioactive.
PCR - correct answer ✔✔-polymerase chain reaction
- technique for making many copies of a defined segment of DNA.
Electrophoresis - correct answer ✔✔method of separating serum proteins by electrical charge
Three possible outcomes of electrophoresis - correct answer ✔✔1) Match
2) Exclusion
Arrestee Bill - correct answer ✔✔1) all people arrested for felony charges will be required to
give a DNA sample.
2) Can get a hit in those 90 days and use that information even if they aren't charged.
Jesse James - correct answer ✔✔1) Historians say he died by being shot in the back by a
member of his own outlaw gang while straightening a picture on the wall of his home.
2) He was apparently buried on the family homestead near Kearney, MO. The remains were
moved in 1902 and reburied next to his wife.
