Final answer:
The common order of steps in a viral reproductive cycle is Attachment, Entry, Integration (optional), Synthesis of viral components, Viral Assembly, and Viral Release; option C is correct.
Step-by-step explanation:
The correct order of the steps in a viral reproductive cycle is: Attachment, Entry, Integration (optional), Synthesis of viral components, Viral Assembly, Viral Release. Therefore, among the given options, the accurate sequence is represented by option C: Attachment, entry, integration, synthesis of viral components, viral assembly, viral release. This sequence follows the typical path of viral infection and reproduction within a host cell.
In detail, a virus first attaches itself to a specific receptor on the host cell. After attachment, the virus enters the host cell through a process called entry. If the virus integrates its genome with the host's, this is the integration step (though it's optional and not present in all viruses).
Following entry (and integration if it occurs), the virus begins the synthesis of its components using the host cell's machinery. Next is the assembly of the new viral particles, and finally, the new virions are released from the host cell in the last stage known as viral release, ready to infect adjacent cells and repeat the replication cycle.
