Question

Why is Selection so important in genetic engineering? Using these antibiotics, which selection technique could be used to differentiate between recombinant and non-recombinant cells?​

Answer 1

Answer:

Adding an antibiotic resistance gene to the plasmid solves both problems at once – it allows a scientist to easily detect plasmid-containing bacteria when the cells are grown on selective media, and provides those bacteria with a pressure to keep your plasmid.
