Question

Making anti-viral drugs is more difficult than making anti-bacterial medicines because:

• A. viruses are very small in size
• B. viruses are on the borderline of living and nonliving
• C. viruses use the host cell machinery to grow and divide
• D. viruses are surrounded by a protein coat

Answer 1

The correct option is B

viruses are on the borderline of living and nonliving

It is difficult to make anti-viral drugs because viruses exist as non-living outside a host cell and so they cannot be called as living or non-living. Hence, it is difficult to study them and find a cure against the infections caused by viruses. Viruses also have an ability to modify themselves frequently giving rise to different strains. Therefore, it is very difficult to make drugs against a particular virus.
