Question

Knockout mice have been genetically altered to knock out specific genes. How are these mice most often used in research?

a. to examine defects in DNA structure in those regions that have been altered
b. to determine the role of proteins coded for by those genes that are knocked out
c. to study DNA replication in the defective genes (those that have been altered)
d. to study the effect of radiation on DNA

Answer 1

Option C is the correct answer

C. to study DNA replication in the defective genes (those that have been altered)

Step-by-step explanation:

They are used to study the roles of genes which have been altered but whose function is yet to be determined.
