Knockout mice have been genetically altered to knock out specific genes. How are these mice most often used in research?
A) to study DNA replication in the defective genes those that have been altered)
B) to examine defects in DNA structure in those regions that have been altered
C) to determine the role of proteins coded for by those genes that are knocked out
D) to study the effect of radiation on DNA

Question

Quizplus · Accepted Answer

Knockout mice are most commonly used in research to determine the role of proteins that are coded for by the genes that have been knocked out. This can help researchers understand the normal function of these proteins and their contribution to various biological processes. Studying DNA replication, defects in DNA structure, and the effects of radiation on DNA can also be done with knockout mice, but these are less common uses.
