Question

In a lytic cycle of replication, release of phages involves _____.

a. the bacterial cell bursts open
b. keeping the host cell alive
c. contact with another uninfected bacterium
d. exocytosis of phages across the cell wall

Answer 1

The release of phages in the lytic cycle involves the bacterial cell bursting open, not exocytosis. Proteins like holing or lysozyme disrupt the cell wall, leading to the release of new virions.

Step-by-step explanation:

In a lytic cycle of replication, the release of phages involves the bacterial cell bursting open. During the lytic cycle, phage proteins such as holing or lysozyme disrupt the bacterial cell wall, leading to cell lysis. This process culminates in the mature viruses bursting out and being liberated into the environment to infect new cells. Exocytosis is not involved in this process; rather, the cell is destroyed as the new virions are released.
