Amplification

Generally, amplification is a basic process sometimes seen in nature, and often used in processes which involve a signal which must be made stronger.
In linguistics, an amplification is a figure of speech that adds importance to or makes the most of a statement, to increase its rhetorical effect.
In molecular biology, amplification (polymerase chain reaction or PCR) is the method for creating multiple copies of DNA (or RNA) without using a living organism, such as E. coli or yeast.
