Biomed EOC Exam Questions And Accurate Answers
100% Verified
Are all fats the same? - ANSWER Not all fats are the same. Fats have all different
purposes and jobs that they do in your body
What is the difference between saturated and unsaturated fats? - ANSWER saturated-
solid at room temp, not essential, harder to digest, found in animals, bad fat
unsaturated- liquid at room temp, found in plants and oils, good fat
Why are unsaturated fats considered healthier than saturated ones? - ANSWER
Saturated fats are not easily removed by the bodies proteins, while unsaturated fats are
What is cholesterol? - ANSWER A lipid that is very important in your body, essential for a
person to live, but can also turn into something very bad for you if you take into to much
of the bad cholesterol, HDL
Why are so many foods advertised as non-fat and cholesterol-free? - ANSWER It is a
healthier choice than getting foods that have high levels of LDL and "fatty acids" that
forms fat in our body
What are LDL and HDL? - ANSWER LDL and HDL are forms of cholesterol-carrying
particles in the blood. LDL, or low density lipoprotein, is the bad type of choesterol that
forms plague in you blood vessels and causes blood to not be able to move fluently
through you blood vessel. HDL, or high density lipoprotein, is the good tyoe of
cholesterol that decresed the plague build-up in you blood vessels and carries extra
cholesterol that embeds in your blood vessel walls back to the liver where is can go to
the cell wall and go to the LDL receptor sites
Why are there so many drugs available to lower cholesterol or LDL? - ANSWER It can be
very deadly and completely block blood from flowing in your blood vessels
, How are LDL, HDL, and cholesterol related to heart disease? - ANSWER It can stop your
heart from pumping and cause a heart attack or stroke. HDL is related to the heart
because to little of it can slow the blood flow through your artery walls and cause a
heart attack or stroke also. You want a lot of HDL to lower your LDL levels and reduce
the risk of heart damage
How do crime scene investigators get enough DNA evidence from a single drop of
blood? - ANSWER By amplification, PCR
What is PCR? - ANSWER Polymerase chain reaction, or a laboratory technique for
amplifing DNA to get more copies of the blood to try to diagonos a patient that has a
disorder because of a mutation within the gene in the DNA
How is DNA analyzed without sequencing it? - ANSWER DNA is analyzed by running the
DNA in a electrophoresis, which organizes the DNA by size. The DNA is exponential, or
gets greater in size as it gets farther down the gel
What does PCR do and how does it work? - ANSWER PCR isolates the DNA and it works
by unzipping sections of DNA with the restriction endonuclease and isolating the DNA
with the mutation. The section of the DNA gets smaller and smaller with every unzipping
it does and gets closer to the mutation
Can genetic diseases or disorders be diagnosed using a small blood or saliva sample
from a patient? - ANSWER Yes, by amplification and PCR
Why are DNA tests on television programs and movies shown as patterns of stripes or
bands on film or in gels? - ANSWER They are shown like this becuase in the process of
RFLP, the DNA get cut into bands by enzymes depending on how much DNA there is,
polymerase, and catorgorize themselves as little bands on the top of the gel to bigger
bands near the bottom of the gel. The bands are linear shaped, or in a straight line
What is gel electrophoresis and how are the results interpreted? - ANSWER Gel
electrophoresis is a gel in which DNA travels through with electric charges. Restriction
endonulcease cuts DNA into fragments of specific lengths that create several different
