Chapter 1, Problem 1CTQ
Summary Introduction
To determine:
One argument in support and against the statement that the “Viruses are living microorganisms”.
Concept introduction:
The living organism varies from the single celled prokaryotic cells to the multicellular eukaryotic cells. Some of the living organisms can move, while some cannot.

Provide evidence in support of or refuting the following statement: Viruses are simple cellular agents of disease
Gain of Function research, defined as:
"medical research that genetically alters an organism in a way that may enhance the biological functions of gene products."
The worry is that this type of research will lead to the release of dangerous viruses and is unethical; others believe it is necessary to treat future pandemics
is Gain of Function research unethical? Why?
Please use scholarly literature

Which of the following is NOT true about Koch's postulates?
First developed by Robert Koch, the pioneering German microbiologist
In the first step, the microbe that causes a naturally occurring disease is cultured from a "wild"
(non-laboratory) animal which has that disease
None of the other four answers (All are true about Koch's Postulates)
They represent a process for showing a causal association between a specific microbe and a
disease
If the same microbe from a diseased "wild" (non-laboratory) host causes the same disease in a
lab animal and it can be cultured from that lab animal, this proves that the microbe is the cause
of the naturally occurring disease
