Now, once we form the modified gene, once we form the recombinant gene, the next logical step is to clone our gene to make many copies. And one way by which we can amplify the gene gene of interest is by introducing that novel gene into a cell and allowing the cell to basically replicate that gene many, many times. Now, we can't simply take a gene and place it into a cell. We first have to find a vector. And a vector is simply some type of carrier that can actually take that gene and bring it into that cell without the cell destroying that DNA molecule. And one typical carrier or one typical vector that we use is a bacterial plasma.
