Question

Which of the following statements is not correct for viruses?

• A. Viruses are obligate parasites
• B. Viruses can multiply only when they are inside the living cells
• C. Viruses cannot pass through bacterial filters
• D. Viruses are made up of protein and DNA or RNA (never both DNA and RNA)

Answer 1

The correct option is C Viruses cannot pass through bacterial filters

Viruses are made up of protein and DNA or RNA (never both DNA and RNA). Virus is a small infectious agent that replicates only inside the living cells of other organisms (obligate parasites). Viruses can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea. Viruses can pass through bacterial proof filters as they are smaller than bacteria.
