There are three ways in which exogenous dna can be
introduced into a bacterial genome. These are; transduction, transformation and
conjugation. Transduction is the introduction of exogenous material into bacteria
by viruses; conjugation is exchange of genetic material between bacteria sexual
through reproduction; while transformation
is uptake of exogenous dna by bacteria, from its surrounding, through the
bacterial membrane.
Answer:
