It looks like you're asking about the lytic cycle of viral replication and how some viruses propagate. Here's a breakdown of the correct process for the lytic cycle among the options you've provided:
-
Using the host cell's machinery to replicate: Viruses inject their genetic material into a host cell and use the host's cellular machinery (enzymes, ribosomes, etc.) to replicate their own genetic material and produce viral proteins.
-
Assembling new viruses: The viral components (newly synthesized viral genetic material and proteins) are then assembled into complete viral particles.
-
Lysis of the host cell: Once the new viruses are assembled, they cause the host cell to burst (lyse), releasing the new viruses to infect other cells.
Based on your provided options, the closest description is:
- Incorporating their genetic material into the host cell's genetic material to create new viruses: This closely resembles what happens in the lytic cycle, as viruses indeed use the host's machinery but don't necessarily merge their genetic material into the host's DNA; instead, they use it to create copies.
Options like "undergoing mitosis" or "masosis" are not accurate for viruses, as these processes are related to cell division in eukaryotes, not viral replication.
In summary, the process primarily involves the virus hijacking the host cell's machinery to replicate itself and ultimately leading to the cell's destruction to release new viral particles.
