Require bacterial cells to grow
We’ll focus on the T2 phage.
• It consists of 2 main parts• Head: Icosahedral shape • Tail: hollow tube.
• DNA is in the head, and the shell is made of protein.
• It survives by the ‘Lytic Cycle’!

Radioactive sulfur (protein) is found predominantly in the supernatant.
Radioactive phosphorus (DNA) is found predominantly in the cell fraction.
