Positively charged divalent calcium ions(Ca2+) attract both the negatively charged DNA backbone (phosphate) and the negatively charged groups in the lipopolysaccharides inner core. While, Incubation on ice will reduce the thermal motion of molecules and so further promote the binding process. Upon heat shock, the cell membrane alters in a way that allows DNA uptake without losing the internal contents.
