blood, it can stimulate the production of several different clones of plasma cells. These produci
a variety of antibodies (polyclonal antibodies). Suggest an explanation for this. (4)
Answer
When MRSA enters the blood, it triggers the immune system to produce a variety of antibodies to fight against the infection. This results in the production of different clones of plasma cells, each producing a unique antibody that can recognize and bind to different parts of the MRSA bacterium. This diversity of antibodies is necessary to effectively neutralize the MRSA infection and prevent it from spreading further.
