Which term describes the mechanism by which an enveloped virus exits a host cell?

• A. Endocytosis
• B. Budding
• C. Lysis
• D. Conjugation

Answer: (B)

Verified step by step guidance

1. Understand that enveloped viruses acquire their lipid envelope from the host cell membrane during the exit process.
2. Recall that endocytosis is a process by which cells internalize substances, so it is related to virus entry, not exit.
3. Recognize that lysis involves the breaking open of the host cell, which is common for non-enveloped viruses but not typical for enveloped viruses.
4. Know that conjugation is a bacterial process for DNA transfer and is unrelated to viral exit mechanisms.
5. Identify that 'budding' is the process where enveloped viruses exit the host cell by wrapping themselves in a portion of the host's membrane, forming their envelope.
