Answer 1

1) Antigenic drift is the natural process by which the microorganisms such as viruses accumulate certain mutations in their genes over a period of time. These mutations are required for the virus to evolve and survive in the changing environment. This antigenic drift can be due to host immune system, natural selection and evolution. Show the answer for this question is option 4 (All of the above).

2) The bias of the immune system to produce neutralizing antibodies against specific structural components of a virus, is know as monoclonal antibody production (Option 2).
