what is antibiotic selection? Correct Answer-the most resistant cells surviving when antibiotic resistance is around where can abx selection occur? Correct Answer-anywhere that bacteria and abx is present name a common use for abx selection in microbiological research Correct Answer-identifying particular cells that contain a DNA of interest -ex: plasma, transform cells w a plasma and plate them on an agar Why does virtually every plasmid used for scientific research contain an antibio...
