The sinister and eerie T4 phage waits in ambush. When it detects its
victim, T4 rotates quickly, pointing its thirty-faceted isosahedral head
away from its prey. Now it is ready for the attack.

Attached to its head by a collared neck is T4's tail, consisting of a
hollow core surrounded by a contractile sheath. At its base is a spiked
end plate from which six fibers emerge.

When its victim draws near, T4 uses its spikes and fibers to grasp onto
its prey. Once it has affixed itself, the sheath violently contracts,
driving the hollow core into the victim's body. Once the body cavity has
been penetrated, it now uses the core as a syringe, injecting the contents
of its head into the victim.

After 1 minute:   The victim's DNA begins to disintergrate. All production of
                  native proteins cease. Initiation of the production of the
                  alien T4 proteins begins The first proteins produced then
                  direct the following steps.

After 5 minutes:  Replication of T4 phage DNA begins.

After 8 minutes:  Initiation of production of structural proteins, which will
                  form the bodies of the new T4 phages.

After 13 minutes: First complete replica of the T4 invader is produced.

After 25 minutes: The final protein is synthesised - lysozyme - which causes
                  the victim to burst open, and 200 identical T4 phages emerge,
                  each fully armed and ready to search out more prey.

The deadly T4 phage neither eats nor sleeps. It is always on the hunt. 
In some cases, when victim supply is low, it will not produce lysozyme,
but rather, lay dormant within the victim's DNA, lurking until the time is
right to begin mass production again, even if it means waiting for the
prey to reproduce several times. Because the T4 has encoded itself into
the victim's DNA sequence, each of the offspring will carry with it copies
of T4.....
