The use of an antibiotic-resistance gene on a plasmid used in genetic engineering allows for direct selection of cells that have successfully taken up the plasmid and incorporated the desired gene. This is because only cells containing the antibiotic-resistance gene will be able to survive the selective pressure of antibiotics, allowing for easy selection of successful transformations.
