It's A right .. !


No Addicudo, its D. No colonies grow after the addition of DNAse, that means all the DNA have been destroyed. Only in transformation the DNA can be destroyed by adding DNAse to the culture medium as only there the DNAs are not protected from digestion by these enzymes.


Oo .. OK .. Got the big picture now .. !!! THanks Doc179


okay .. one last to this post .. There is no such thing as Transposition for resistance mechanisms .. THE others are mechanisms of resistance .. I know .. BUt Transposition .. ?


I hope I understood your qn well wink
Anyway..I will tell you what I think and if that does not address your qn pls let me know.
I guess by tranposition they mean insertion of a transposon which sometimes has the resistance for antibiotics genes and gets inserted into the plasmid which by conjugation gets transported into another bacterial cell making that resistant for this antibiotic. I have come across such a qn in Kaplan micro notes.


huMMm may be .. !! tasnsposon insertion = transposition .. !!
