Final answer:
Adenovirus uses E1A protein to inhibit the apoptosis pathways in infected cells, allowing the virus to replicate and assemble its components before the cell can initiate programmed cell death.
Step-by-step explanation:
The question addresses how Adenovirus prevents apoptosis with the presence of its E1A protein. Apoptosis, or programmed cell death, is a mechanism that helps to control the spread of viral infections by eliminating infected cells before a virus can replicate and assemble new virions.
For a virus like Adenovirus, preventing early apoptosis allows it to maximize the production of its progeny. The E1A protein is known to interfere with apoptosis by inhibiting pathways that lead to cell death.
While the detailed mechanism involves a complex interplay between viral and host cell proteins, it is notable that viruses like Adenovirus can modulate host cell pathways to survive and propagate within the host organism.
