Researchers can insert DNA fragments or genes into a plasmid vector, creating a so-called recombinant plasmid. This plasmid can be introduced into a bacterium by way of the process called ...

Immunizing the host with a piece of viral DNA rather than an antigenic protein fragment of the virus, helps to stimulate the generation of cell-mediated immunity (Fig. 2). DNA vaccines contain the ...

Figure 1: Expression of reporter gene constructs derived from the gcy-5, lim-6 and lsy-6 genes. One potential explanation for our observations is that the vector backbone may dictate the packaging ...
