Now, one common example of transformation is the following. Basically, we take a cell or we take a bacterial cell that contains the genes that are harmful to eukaryotic cells. So we kill off those harmful bacterial cells, and then we bring those harmful bacterial cells that are dead next to living bacterial cells that are living but which are harmful. Over time, those harmless bacterial cells will eventually become harmful because of transformation. So basically what happens is our harmless bacterial cell takes up genetic information, our fragments of DNA that came from the harmful bacterial cell, and takes them and brings them into the cell and then incorporates that into its own DNA. And then when that DNA is transcribed, when we transcribe this section, we build proteins that basically end up harming some type of eukaryotic cell.
