10.7A: The Lytic Life Cycle of Bacteriophages - Biology LibreTexts
a
A virus injects its genetic material into the host cell, copies itself using the host's structures and resources, and then forms new viruses that burst out of the host cell.
b
A virus lays eggs on the host cell’s protein coat, which then hatch and move on to infect other cells.
c
A virus copies its own genetic material and then splits its cell membranes in half to form two identical viruses.
d
The viral DNA incorporates itself with the host cell’s and replicates whenever the host cell replicates itself.

The correct summary of the lytic cycle is:
a: A virus injects its genetic material into the host cell, copies itself using the host's structures and resources, and then forms new viruses that burst out of the host cell.
In the lytic cycle, the virus takes over the host cell, replicates its genetic material, assembles new viral particles, and ultimately causes the cell to lyse (burst), releasing new viruses to infect additional cells.
