how is antigenic drift beneficial for viruses
a. it changes how gene code for antigens
b. it leads to less mrna which is easier to copy
c. it creates a variety of immune response in the host organisms
d. it makes them unrecognizable to immune system
d. it makes them unrecognizable to immune system
Antigenic drift is beneficial for viruses because it allows them to change their surface proteins (antigens) slightly over time, making it harder for the immune system to recognize and respond to them. This ultimately allows the virus to evade the host's immune response and continue to infect and replicate within the host.
