Scientists are now working to synthesize the cellular proteins to which these viruses attach.

The virus can attach only to cells that have the right receptors - compatible molecules on their surfaces.

If the virus attaches itself to a program used every day, the damage will occur immediately.

For example, a virus might attach itself to a program such as a spreadsheet program.

The virus attaches to and enters the person's white blood cells.

But such patients are seldom studied, so it is not known why the virus attaches there.

Many viruses attach to molecules present on the surface of red blood cells.

A cold begins when a cold virus attaches to the lining of your nose or throat.

The S protein helps the virus attach and enter human cells.

A virus attaches itself to other computer programs secretively.
