Question
**Understanding the Viral Replication Cycle** --- **Question:** Which is the usual order of a viral replication cycle when it is making new virions? **Options:** 1. Host recognition > replication > entry > uncoating > release 2. Uncoating > host recognition > replication > entry > release 3. Prophase > metaphase > anaphase > telophase > cytokinesis 4. Host recognition > entry > uncoating > replication > release --- **Explanation:** In the context of virology, understanding the steps involved in the viral replication cycle is crucial for comprehending how viruses infect host cells and produce new virions. Here’s a breakdown of each option: 1. **Host recognition > replication > entry > uncoating > release**: This sequence is incorrect. While host recognition and release are involved in the viral replication cycle, the order of the processes here is not accurate. 2. **Uncoating > host recognition > replication > entry > release**: This sequence is also incorrect. Uncoating typically occurs after the virus has entered the host cell. 3. **Prophase > metaphase > anaphase > telophase > cytokinesis**: This sequence describes the stages of mitosis, which is the process of cell division, not the viral replication cycle. 4. **Host recognition > entry > uncoating > replication > release**: This is the correct sequence. Here’s what happens at each step: - **Host recognition**: The virus identifies and binds to receptors on the surface of the host cell. - **Entry**: The virus or its genetic material enters the host cell. - **Uncoating**: The viral capsid is removed, releasing the viral genome into the host cell. - **Replication**: The host cell’s machinery is used to replicate the viral genome and produce viral proteins. - **Release**: New virions are assembled and released from the host cell to infect additional cells. In summary, the usual order of a viral replication cycle when making new virions is accurately described by the fourth option: **Host recognition > entry > uncoating > replication > release**. Understanding this cycle is vital for the study of viruses and the development of antiviral therapies.
