Question
What is a significant difference between lytic and lysogenic viral growth?
Solution
The significant difference between lytic and lysogenic viral growth lies in the process and outcome of the infection.
-
Lytic Cycle: In the lytic cycle, the virus takes control of the host cell's machinery to replicate its own genetic material and produce new virus particles. This process is rapid and results in the destruction or lysis of the host cell, releasing the new viruses to infect other cells. This cycle leads to symptoms of viral infection.
-
Lysogenic Cycle: In the lysogenic cycle, the virus integrates its genetic material into the host cell's DNA without causing immediate destruction of the host cell. The viral DNA (prophage) is replicated along with the host cell's DNA each time the cell divides, spreading the virus without killing the host cell. This can continue for many generations of cells. The virus remains dormant until a trigger causes it to enter the lytic cycle.
So, the significant difference is that the lytic cycle results in the destruction of the host cell, while the lysogenic cycle allows the virus to spread without killing the host cell.
