Understand the lytic cycle: The lytic cycle is a process by which a bacteriophage infects a bacterial cell, replicates, and eventually causes the cell to burst, releasing new phage particles.
Step 1 - Attachment: The bacteriophage attaches to the surface of the bacterial cell. This is the initial step where the phage recognizes and binds to specific receptors on the host cell.
Step 2 - Penetration: After attachment, the phage injects its genetic material into the bacterial cell. This involves the transfer of DNA or RNA from the phage into the host cell.
Step 3 - Biosynthesis: The phage's genetic material takes over the host cell's machinery to produce phage components. This includes the synthesis of phage DNA and proteins necessary for new phage particles.
Step 4 - Maturation and Step 5 - Release: Maturation involves the assembly of phage components into complete viral particles. Finally, during release, the bacterial cell lyses (bursts), releasing the newly formed phages to infect other cells.
