Title: Re: Why might transposon mutagenesis be favored over chemical mutagenesis? Post by: bio_man on Mar 26, 2012 The use of transposons such as Tn5 and Tn10 is an excellent way to positively select for mutants using kanamycin or tetracycline (respectively) in a growth medium. This is very useful, especially when there is no other way to select for the newly generated mutants, because only the mutants containing the Tn-inserted antibiotic resistance marker will grow.
