Discuss with your teacher what does 'a suitable gene' mean in the context of $DNA$ vaccines.

(N/A) 'suitable gene' refers to a specific $DNA$ segment that encodes for a specific antigen (protein). When this $DNA$ is introduced into the host's cells, the cells express this gene to produce the antigen. This antigen is then recognized by the host's immune system, which triggers an immune response, leading to the production of antibodies and memory cells, thereby providing immunity against the specific pathogen.
