Bacterial Genetic Recombination

Bacterial Genetic Recombination. What is the main source of genetic recombination in bacteria? Mutations What are the other sources of recombination?. Transposase recognizes the inverted repeats. Targeted inverted repeats are cut, and the target is cut, then the transposon is inserted.
