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 ...

Note: for plasmid DNA the size is the entire plasmid, vector plus insert. For plasmid DNA you may use the “divide by 20 rule” where you divide the size of the plasmid by 20 to determine the nanograms ...
