What term is used to refer to the process in which dna can be introduced into host bacterial cells?

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.
