Almost all viruses are made of a nucleic acid core, containing the genetic material, and a capsid, a coat composed of a few proteins. Viruses come in different sizes and shapes. Some viruses are made up of up to 20 triangle shaped surfaces, others look like fine threads, and some look like a sphere.

Viruses are made up of nucleic acid (DNA or RNA) wrapped up in a protein coat called a capsid. The capsid of some viruses may also be covered with a plasma membrane.

The genetic material. RNA or DNA. And generally a protein coat of various design. The T-4 virus looks to me as a landing craft, with struts for support. This is a bacteriophage, which does " land " on bacteria, and injects it's genetic material into the bacteria. It then, simply, high jacks the bacterias cellular machinery to turn out more copies of itself.
