Bacteriophage
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’!

T2 Phage’s Life Cycle
We survive by the wonderful procedure called the ‘Lytic Cycle’!

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