Question:
Do DNA, RNA or both have a helix formation?
Answer:
Only DNA
Question:
Is DNA self-replicating?
Answer:
Yes
,Question:
Is RNA self-replicating?
Answer:
No
Question:
Where is DNA located in a eukaryotic cell?
Answer:
Nucleus, Mitochondria, Chloroplasts
Question:
Where is RNA located in a eukaryotic cell?
Answer:
Nucleus, Cytoplasm, Ribosomes
Question:
What is a sporadic disease?
Answer:
Dispersed cases with rare occurrence in a population (Examples: tetanus,
rabies, and plague in the US)
,Question:
What is an endemic disease?
Answer:
Disease always present at a baseline in a particular geographical region or
population (Examples: malaria, common cold, HIV)
Question:
What is an epidemic disease?
Answer:
Frequency of disease increases above the expected number in a specific area
and time frame (Examples: Lyme disease, West Nile, polio). Note: An
epidemic is called an outbreak if it occurs in a small geographic area. A cluster
is a group of cases occurring together in a time and place at a greater number
than expected (even if an expected case number isn't known).
Question:
What is a pandemic disease?
Answer:
Exponential number of infections covering multiple countries or geographical
areas (Influenza, COVID-19)
, Question:
What is a prion?
Answer:
An infectious protein. In some encephalopathies, the protein is misfolded,
like in scrapie or
Question:
Koch's postulates include re-isolating the pathogen from the experimental
subject after inducing the disease. What does this step confirm?
Answer:
That the pathogen is the same one that was originally isolated and is the cause
of the disease.
Question:
True or False: The presence of a pathogen alone is always sufficient to trigger
an infection in a host.
Answer:
False
