Core Concept

The primary reason for the use of antibiotic resistance genes as a selection tool in genetic engineering is the ability to selectively kill unwanted cells. This allows researchers to isolate cells with the desired genetic modification. Increased efficiency of gene transfer and enhanced gene expression are potential benefits, but not the primary reason. Reduced cost of production is not directly related to the use of antibiotic resistance genes.
