The basic idea and rationale behind the study of "knockout mice" is that ________.
A) if a gene is used in a particular function, then knocking out the gene should create a deficit in that function
B) mice who are "knocked out" after receiving a tranquilizer will show diminished recall abilities upon regaining consciousness
C) researchers cannot manipulate a mouse's genetic composition so as to impact its memory
D) extremely aggressive mice tend to recall various maze routes better than less aggressive ones

Question

Quizplus · Accepted Answer

The basic idea behind the study of "knockout mice" is to disable or "knock out" a specific gene in order to determine the gene's function. If the knocked-out gene is used in a particular function, then knocking out the gene should create a deficit in that function. This allows researchers to study the specific role of a gene in a particular biological process. Option B and D are not related to the concept of knockout mice, and option C is incorrect as researchers are able to manipulate a mouse's genetic composition through genetic engineering techniques.
