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.
In this electron micrograph of bacteriophages attached to a bacterial cell, the viruses are the size and shape of coliphage T1. To enter a host cell, bacteriophages attach to specific receptors on the surface of bacteria, including lipopolysaccharides, teichoic acids, proteins, or even flagella.hages are classified by the International Committee on Taxonomy of Viruses (ICTV) according to morphology and nucleic acid. Nineteen families are currently recognized by the ICTV that infect bacteria and archaea. Of these, only two families have RNA genomes and only five families are enveloped.
