Webbacterial species. The selectable marker in Tn5Tn5Tn5 is a gene that confers resistance to the antibiotic kanamycin. Thus bacteria without Tn5Tn5Tn5 are sensitive to kanamycin (Kans), whereas bacteria that have Tn5Tn5Tn5 inserted into the chromosome are resistant to kanamycin (Kanr). WebResistance to zeocin is conferred by the Sh ble gene product, which binds the antibiotic and prevents it from binding DNA. This selection agent is effective in multiple cell types, so eukaryotic expression vectors only need to carry one drug selection marker.

"Kanamycin works by interfering with protein synthesis. It binds to the 30S subunit of the bacterial ribosome. This results in incorrect alignment with the mRNA and eventually leads to a misread that causes the wrong amino acid to be placed into the peptide. This leads to nonfunctional peptide chains.
