Question

A DNA vaccine involves placing genes into a plasmid and introducing the plasmid into human cells. Human cells then transcribe and translate the genes to produce antigen which immunize the recipient. What is the source of the genes being introduced?

Answer 1

Bacterial source

Step-by-step explanation:

Given the bacterial source of the genes introduced, the antigens produced on the cell surface are bacterial and hence bacterial pathogens will recognise the host cells as bacterial cells, indirectly tricking the bacterial cells to prevent an infection. Therefore, this immunizes the recipients by preventing an bacterial infection in the recepient.
