Question

Which of the following is the largest virus?

• A. Penicillium virus
• B. Wound tumour virus
• C. Pox virus
• D. None of the above

Answer 1

Answer: (C)

Pox virus

The largest virus is the pox virus, around 250 to 300 microns. The infectious viral particles have the enzymes required for replication within the virion and hence, the virus has a large size. These viruses are different from other viruses in their ability to replicate inside the infected cytoplasm independently. So, the correct answer is option C.
