What is a Bacteriophage?

Bacteriophages are viruses that infect bacteria. Bacteriophages can have a protein "tail" attached to the capsid (protein coat that envelopes the genetic material), which is used to infect the host bacteria.

What is a Virus?

Scientists have long sought to uncover the structure and function of viruses. Viruses are unique -- they have been classified as both living and nonliving at various points in the history of biology.

A virus particle, also known as a virion, is essentially a nucleic acid (DNA or RNA) enclosed in a protein shell or coat. Viruses are extremely small, approximately 15 - 25 nanometers in diameter.

Bacteriophage Animations

Below are some animations of the lytic life cycle of a bacteriophage.

The bacteriophage attaches to the cell wall of a bacterium.

Animation B
The bacteriophage injects its genome into the bacterium.

Animation C
This animation shows the replication of the viral genome.

Animation D
Bacteriophages are released by lysis.

Animation E
Summary of the entire lytic life cycle of a bacteriophage.
