this presentation is based on bacterial recombination and how bacteria recombine with different techniques like conjugation transduction and transformation what are the various techniques which are used for transformation what are experimental methods which are used like electroportation. i also described about the dna repair system DNA repair system is well decscribed in the molecular biology of the gene written by JAMES D. WATSON you can get the complete knowledge with the help of this book.Here i shortly summarize the repair mechanism like nucleotide base excision repair mismatch repair sos repair. i also give some information about disease associated with defective DNA repair system
