WebThe lytic cycle involves the reproduction of viruses using a host cell to manufacture more viruses; the viruses then burst out of the cell. The lysogenic cycle involves the incorporation of the viral genome into the host cell genome, infecting it from within. What is the main difference between a lytic and lysogenic cycle?

Define bacteriophage Bacteriophages, also known as phages, are viruses that infect and replicate only in bacterial cells. 3. Define lytic cycle In the lytic cycle, viruses produce new copies of themselves inside a host cell before bursting outside the cell.

WebJan 10, 2024 · The lytic cycle is known as the active cycle, whereas the lysogenic cycle is the dormant phase of the virus. Similar to the lytic cycle, it begins with the attachment and penetration of the virus. Once the viral DNA has been inserted into the cell, the host is now said to be infected. Here is where the main difference between the two cycles occurs. WebThe enzyme lysozyme is used by the T4 phage to assist in the injection of its DNA into the target cell. true. Place the steps of T4 phage replication into the correct sequence. Attachment—phages attach to receptors on bacterial surface.
