fluids)
Manner of death - Correct Answers -Type of death (i.e. homicide)
Cause of death - Correct Answers -How it happened (i.e. gunshot wound)
Mechanism of death - Correct Answers -What happened medically (i.e. exsanguination)
Glastier equation formula - Correct Answers -(98.7 degrees fahrenheit - the rectal
temperature) / (1.5)
Nucleotide - Correct Answers -building block of DNA
Characteristics of HDL cholesterol - Correct Answers -High density (protein>fat)
Absorbs cholesterol in the body
What type of cholesterol carries more cholesterol? - Correct Answers -LDL
What type of cholesterol has more protein in the molecule? - Correct Answers -HDL
What type of cholesterol should have a level BELOW 100 mg/dL? - Correct Answers -
LDL
What type of cholesterol should have a level ABOVE 40 mg/dL - Correct Answers -HDL
MODIFIABLE risks for developing heart disease - Correct Answers -high blood
pressure, high LDL, smoking/secondhand smoke exposure, obesity, unhealthy diet
NON-MODIFIABLE risks for developing heart disease - Correct Answers -family history
, What is sickle cell anemia? - Correct Answers -A genetic blood disorder in which your
red blood cells are "sickled" due to a lack of oxygen
What is HIPAA? - Correct Answers -Health Insurance Portability and Accountability Act,
a federal law that protects patients' safety and privacy
In a gram staining test, which bacteria stains pink? - Correct Answers -gram negative
What are the steps of gram staining test? - Correct Answers -Primary stain
Fixing agent
Decolorization w/ ethanol
Counterstaining w/ safranin
4 bases of DNA - Correct Answers -Adenine, Thymine, Guanine, Cytosine (A&T C&G)
What is a purine? - Correct Answers -One of two chemical compounds used to make up
DNA and RNA, made up of nitrogen and carbon (adenine and guanine)
What is a pyrimidine? - Correct Answers -One of two chemical compounds used to
make up DNA and RNA, made up of carbon and hydrogen (cytosine, thymine, uracil)
Which base is NOT present in RNA - Correct Answers -Thymine (replaced by uracil)
What do restriction enzymes do? - Correct Answers -Cut DNA at specific sights
What is the purpose of gel electrophoresis? - Correct Answers -Seperate DNA
fragments by size, makes them easier to study/analyze
What way does DNA run on the gel? - Correct Answers -Towards the positive charge
How does DNA differ from person to person? - Correct Answers -The cuts make DNA
fragments. Comparing the sizes of the fragments can show differences in the DNA
code.
What strand would bind with this DNA strand?
CTTAGAGTC - Correct Answers -GAATCTCAG
What's an RFLP? - Correct Answers -Restriction fragment length polymorphism.
Detects different lengths after digestion of DNA samples for similarities amongst people
What does PCR stand for? - Correct Answers -Polymerase Chain Reaction
What is the purpose of PCR? - Correct Answers -To amplify/make more small segments
of DNA
