Bacteriophage T4 is a member of the ICTV family myoviridae, long-tailed viruses with contractile tails. T4 is the namesake of the T4-like virus genus.

Genome Organization
T4 has a circular genetic map[1], but the T4 genome is physically packaged as linear dsDNA. Headful packaging incorporates DNA that is circularly permuted[2] and terminally redundant[3] with respect to the genetic map.
