What is the primary purpose of neomycin in creating mice with knock-ou

1.	What is the primary purpose of neomycin in creating mice with knock-outs in gene X?
A.	neomycin selects for the survival of embryonic stem cells (ES) that have incorporated the mutant gene X anywhere in the genome
B.	neomycin selects for the survival of ES cells that have incorporated the mutant gene in the place of the wild-type gene
C.	neomycin prevents Candida infection during ES cell culture that does not have gene X
D.	neomycin makes the gene X knock - out mice resistant to Candida infection
Answer» B. neomycin selects for the survival of ES cells that have incorporated the mutant gene in the place of the wild-type gene
