We can then place it into a plasma and take that plasmid and place it into a bacterial cell. And that bacterial cell will divide. And as it divides, it will replicate that plasmid. And so we can produce use many identical copies of that recombinant DNA molecule of interest. Now, we can use plasma's vectors or we can also use another type of vector, another type of carrier known as a lambda phage. And a lambda phage is a special type of bacteria phage that infects E. Coli cells.
