And what that means is, in the next step, in step two, we can use gel electrophoresis to basically separate the different fragments based on size up to a size value of 15 KB, where KB is kilo basis. So we run our gelatrophries and those fragments that end up at the bottom are the smallest, while the fragments that end up at the top are the largest. And each one of these fragments contains some type of gene. So now we essentially have these five beakers and in each one of these beakers we have a single type of gene. Now, the problem is we only have one of the genes, but to actually work with them, we have to have many copies of that gene. And so in the next few steps, what we actually want to do is we want to amplify make many copies of each one of these genes.
