A virus injects its DNA into a living cell and has that cell reproduce more of the viral DNA.

You know--the virus floats around, attaches to a cell wall, and injects itself into the cell.

Researchers decided to put copies of normal genes into adenoviruses so that the viruses would inject these genes along with their own genes.

A latent virus first injects its hereditary material (DNA) into the cell using the host cell.

In the first stage, called "penetration," the virus injects its own nucleic acids into a host cell.

A pathway must be opened before the virus can inject its genetic material into the host cell and reproduce itself.

Unhindered by the usual defenses, the virus injects its core into some of the immune system's own cells.

Instead, a biological virus must inject its DNA into a cell.

The virus infected its host from the outside and injected its DNA.

First, Dr. Dilcher said, the virus attaches itself to the external wall of a cell, eats a hole through the wall and injects its genetic material into the cell.
