The cells after transformation are exposed to the selective media, and only cells containing the plasmid may survive. In this way, the antibiotics act as a filter to select only the bacteria containing the plasmid DNA. The vector may also contain other marker genes or reporter genes to facilitate selection of plasmids with cloned inserts.
Description : This image shows a line drawing of a bacterium with its chromosomal DNA and several plasmids within it. The bacterium is drawn as a large oval. Within the bacterium, small to medium size circles illustrate the plasmids, and one long thin closed line that intersects itself repeatedly illustrates the chromosomal DNA.
English: A diagram of a typical prokaryotic cell. This diagram, made in Adobe Illustrator, is an improved version of a similar diagram, Prokaryote cell diagram.svg, which was also made by LadyofHats. Besides general appearance changes, this version adds plasmids and pili, and notes that DNA is circular.

While all bacterial cell walls (with a few exceptions such as extracellular parasites such as Mycoplasma) contain peptidoglycan, not all cell walls have the same overall structures. Since the cell wall is required for bacterial survival, but is absent in some eukaryotes, several antibiotics (notably the penicillins and cephalosporins) stop ...

Description : This image shows a line drawing that compares the activity of non-integrating plasmids, on the top, with episomes, on the bottom, during cell division. The upper half of the image shows a bacterium with its chromosomal DNA and plasmids dividing into two identical bacteria, each with their chromosomal DNA and plasmids.
This is a very well done diagram. It is acurate, labeled, Proposed caption A diagram of a simple Prokaryote. Prokarya are one of the two domains of life, the other being Eukarya. They are characterized by having simple internal structures lacking cell nuclei. The domain Prokarya includes the kindoms Bacteria and Archaea. Articles this image ...
