How do enveloped animal viruses exit their host?
A)budding or exocytosis
B)bursting the host cell
C)rupturing the virus
D)endocytosis

Question

Quizplus · Accepted Answer

Enveloped animal viruses bud off from the host cell membrane, acquiring an envelope as they do so. This process involves the insertion of viral envelope proteins into the host cell membrane, which then assemble around the viral nucleocapsid. The mature virus particle is released from the host cell through exocytosis or budding, which allows it to exit the host cell without causing cell lysis or damage. Option B, bursting the host cell, would be more typical of non-enveloped viruses such as adenoviruses, which can cause cell lysis when they exit their host. Option C, rupturing the virus, is not a process by which a virus exits a host cell. Option D, endocytosis, is a process by which viruses enter host cells, not exit them.
