Confidence votes 61. Viruses attach to living cells by binding to the cell receptors. The receptor site is very much like a jig-saw puzzle and the virus must be shaped to fit the site and to lock in. The virus first sticks to the cell membrane of the host cell. The virus then inserts its DNA/RNA into the cell's cytoplasm.
The virus has a tail which it attaches to the bacterium surface by means of proteinaceous pins.. The tail contracts and the tail plug penetrates the cell wall and underlying membrane, injecting the viral nucleic acids into the cell.iruses are generally classified by the organisms they infect, animals, plants, or bacteria. Since viruses cannot penetrate plant cell walls, virtually all plant viruses are transmitted by insects or other organisms that feed on plants.
