Integra-
tion of exogenous DNA has not been detected using
this method for study (Samoilov et al., 2011). Effective
use of liposomes as agents relies on their ability to
interact by their positive charge with negatively
charged molecules of nucleic acids. As a result a posi-
tively charged complex appears, and it associates with
the negatively charged cell membrane that facilitates
plasmid transfer through the membrane and plasmid
DNA integration into the chromosome
