Where these sections here are our genes and these brown sections are the rest of the DNA sequence of that particular plasmid. Now also notice that the plasmid comes with a special blue section. And what the blue section is, it's a special gene that codes for a special protein that gives the bacterial cell resistance to drugs, resistance to antibiotics. And that will become important in just a moment in step four, as we'll see in just a moment. So let's move on to step three. Once we form these plasmids, we now want to insert these plasmids into actual bacterial cells.
