Antiseptics and antibiotics are used to control bacteria through chemical methods. Antiseptics are bacteriostatic agents (not necessarily killing them) while Antibiotics can also have bacteriostatic and bacteriocidal properties. Some bacteria and fungi produce antibiotics as their natural product. These chemicals, on the other hand, could be synthetic versions of their natural equivalents. The filter paper disc method is a simple and effective way to compare antiseptics and antibiotics based on their ability to stop bacteria from growing.
The picture depicts the relative effectiveness of an antiseptic agent (Iodine) and one antibiotic (ampicillin) against two organisms: S. epidermidis and E. coli. (Distilled water had been used as control).
The millimetre scale clearly shows the zone of inhibition from the edge of the disk to the edge of the growth.

PCR: Polymerase chain reaction is a method widely used in molecular biology to make multiple copies of a specific DNA segment. Using PCR, a single copy of a DNA sequence is exponentially amplified to generate thousands to millions of more copies of the particular DNA segment.
