Bacteriophage is a structure made up of water, proteins, DNA, and RNA. Bacteriophage was first found by Frederick Twort in 1915.
Bacteriophage is very effective. When it comes in contact with a virus it will use its "legs" to cling to the virus' membrane, identify which type of bacteria it is, and proceed to eliminate it. Then, it begins to enter the cell through fusion and releases its' own genetic material into the cell. The cell will start to reproduce its own genetic material, evolving into bacteriophage. The bacteriophage cell will then release an enzyme that will cause it to burst, which allows it to infect the surrounding cells. This will continue until the virus is destroyed.

Step 1: Locating the virus cell.
Step 2: Attaching itself to the cell.
Step 3: Releasing genetic material into the cell. (Destroying it.)
Step 4: Continuing this process until the virus is destroyed.
