Final Answer:
A(n) virion is an individual virus particle outside a host cell that consists of a nucleic acid core, an outer protein coating, and sometimes an outer envelope. option c.
Step-by-step explanation:
Virions play a pivotal role in the life cycle of viruses, serving as the infectious form of the virus when it is outside a host cell. The term "virion" encompasses the complete structure of a virus, including its nucleic acid core, which contains genetic material, an outer protein coating known as the capsid, and in some cases, an additional outer envelope.
These components collectively contribute to the virion's ability to attach to host cells and facilitate the infection process. The nucleic acid core carries the virus's genetic information, guiding the replication and assembly of new virions. The capsid provides protection to the genetic material and assists in the virus's attachment to host cells. In certain viruses, an outer envelope derived from the host cell membrane surrounds the capsid, further aiding in the virus's ability to infect new cells.
Understanding the structure of a virion is fundamental in virology as it helps researchers and healthcare professionals develop strategies to combat viral infections. By targeting specific components of the virion, such as the capsid or envelope, scientists can devise antiviral therapies and vaccines to prevent or treat
