Serology - correct answer ✔✔various types of laboratory tests using reactions of blood serum
and other body fluids
T/F transporting bloody clothing in a plastic bag is acceptable if it is only temporary? - correct
answer ✔✔false
Are white blood cells used in presumptive testing? - correct answer ✔✔no
in a presumptive test what acts as an oxidizing agent? - correct answer ✔✔hydrogen peroxide
3 qualities of a good presumptive test - correct answer ✔✔high sensitivity, high specificity and
easy to use
Chemiluminescence - correct answer ✔✔the emission of light from a chemical reaction
How is hair useful in forensic science? - correct answer ✔✔the hair root has lots of DNA
how are teeth used in forensic science? - correct answer ✔✔teeth can usually be ground up for
DNA
How can entomology be used to get DNA? - correct answer ✔✔maggots can have DNA
extracted from them
, forensic serology labs perform.... - correct answer ✔✔screening, extraction, quantification and
amplification. all of these are done in separate rooms
antigens and antibodies present in type A blood? - correct answer ✔✔antigens: A
antibodies: B
antigens and antibodies present in type AB blood? - correct answer ✔✔antigens: A and B
antibodies: none
antigens and antibodies present in type B blood? - correct answer ✔✔antigens: B
antibodies: A
How can blood typing be used in forensic science? - correct answer ✔✔can be used to eliminate
suspects
PCR - correct answer ✔✔(polymerase chain reaction) a method used to rapidly make multiple
copies of a specific segment of DNA; can be used to make millions of copies of DNA from a very
small amount of DNA
RFLP - correct answer ✔✔Differences in DNA sequence on homologous chromosomes that can
result in different patterns of restriction fragment lengths (DNA segments resulting from
treatment with restriction enzymes); useful as genetic markers for making linkage maps.
differences between RFLP and PCR? - correct answer ✔✔RFLP takes more DNA and takes longer
to perform. RFLP also does not work on degraded DNA
