Question

Which one of these is NOT a reason to use model organisms in research?

a) They grow fast
b) They have a sort life cycle
c) They produce many offspring
d) Their genetic analysis is straightforward
e) They have a small circular genome

Answer 1

The incorrect reason for using model organisms in research is that they have a small circular genome; while true for some, not all model organisms used in research have this characteristic.

Step-by-step explanation:

The reason NOT to use model organisms in research is that they have a small circular genome. While model organisms like bacteria have small circular genomes, not all model organisms do. For example, the fruit fly (Drosophila melanogaster), the mouse (Mus musculus), and the nematode (Caenorhabditis elegans) have larger and more complex genomes. Model organisms are chosen for traits such as fast growth, short life cycles, the production of many offspring, straightforward genetic analysis, and their relevancy to human biological processes. They are essential for understanding genetic, metabolic, and developmental pathways that might be similar across different species.
