This cycle is a type of phage reproduction. Phages either reproduce using the lytic cycle or the lysogenic cycle.

The lytic cycle is a viral reproductive cycle that culminates in death of the host cell. This refers to the last stage of infection, during which the bacterium breaks open and releases the phages that were produced within the cell.

A virulent virus is one that produces only by a lytic cycle.

The process:

1) The phage uses its tail fibers to stick specific receptor sites on the outer surface of the cell.

2) The phage injects its DNA into the cell.

3)The cell's own DNA is hydrolyzed.

4)The cell's metabolic machinery is directed by phage DNA to produce phage protiens and nucleotides. The phage parts come together. Three separate sets of proteins assemble to form phage heads, tails, and tail fibers.

5)The phage then directs production of the lysozyme which digests the cell wall. With a damaged wall, osmosis causes the cell to swell and finally burst, releasing 100 to 200 phage particles.
