Detailed explanation-1: -A complete virus particle is called a virion. The main function of the virion is to deliver its DNA or RNA genome into the host cell so that the genome can be expressed (transcribed and translated) by the host cell. The viral genome, often with associated basic proteins, is packaged inside a symmetric protein capsid .

Detailed explanation-2: -virion, an entire virus particle, consisting of an outer protein shell called a capsid and an inner core of nucleic acid (either ribonucleic or deoxyribonucleic acid-RNA or DNA). The core confers infectivity, and the capsid provides specificity to the virus.

Detailed explanation-3: -Viruses are nucleoproteins. They are non-cellular structures with infectious genetic material. Virions are capsid-encapsulated viruses with DNA or RNA molecules. It has both nucleic acid as well as protein layers.

Detailed explanation-4: -3. Which of the following statements are true about a virion? Sol: (d) An infectious and fully formed viral particle.

Detailed explanation-5: -A fully formed virus that can cause an infection in a host cell is called a virion.
