Medical Interventions Midterm Exam Questions And
Answers
Active immunity - Answer a form of acquired immunity in which the body produces its
own antibodies against disease-causing antigens
anneal - Answer to reduce brittleness and improve toughness by heating and cooling
(metal or glass)
antibiotics - Answer A class of chemical agents that destroy-causing microorganisms
while leaving the patient unharmed
antibody - Answer a substance produced by the body that destroys or inactivates an
antigen that has entered the body
antigen - Answer A protein that, when presented in the blood, stimulates the production
of an antibody
audio gram - Answer informs us about the extent of hearing loss, type, or severity of
impairment
B cells - Answer Cells produced in the bone marrow that produce antibodies for the
purpose of isolating and destroying invading bacteria and viruses.
bacteria - Answer A member of a large group of unicellular microorganisms lacking
organelles and an organized nucleus, including some that can cause disease.
base pairs - Answer Composed of nitrogen based chemicals that bond to form DNA.
Contain chemicals Adenine, Thymine, Guanine, and Cytosine.
, cell parts and functions - Answer Nucleus, plasma membrane, endoplasmic reticulum,
golgi apparatus, lysosomes, mitochondria, nuclear membrane, chlorplast, cell wall
(plants only)
chromosomes - Answer Bodies within the nucleus made in DNA and proteins called the
histones
concentration - Answer A measurement of how much solute exists within a certain
volume of solvent
conjugation - Answer A temporary union of two organisms for the purpose of DNA
transfer.
denaturation - Answer For proteins, a process in which a protein unravels and loses its
native conformation, thereby becoming biologically inactive. For DNA, the separation of
the two strands of the double helix. Denaturation occurs under extreme conditions of
pH, salt concentration, and temperature.
ELISA - Answer Antigen-Antibody re-activity. Tests a patients blood for presence of an
antibody or an antigen (HIV example).
endotoxin - Answer A poison found within the outer membrane of some gram-negative
bacteria that is released only after the death of the bacteria.
enzyme - Answer A protein that catalyzes chemical reactions in an organism
fluorescent markers - Answer Used in nucleotide sequencing to label DNA for specific
nucleotides at the end of the molecule
gel electrophoresis - The technique in which DNA fragments are separated and
analysed by placing a mixture of DNA fragments at one end of a porous gel and applying
