Genetic readout system for correction of a point mutation in plasmid pKsm4021. A mutant kanamycin gene harbored in plasmid pKsm4021 is the target for correction by oligonucleotides. The mutant G is converted to a C by the action of the oligo. Corrected plasmids confer resistance to kanamycin in E.coli strain DH10B after electroporation leading to the genetic readout and colony counts.
