Polymerase chain reaction (PCR) is a laboratory technique used to amplify DNA sequences. The method involves using short DNA sequences called primers to select the portion of the genome to be amplified.olymerase chain reaction (PCR) is a laboratory technique used to amplify DNA sequences.

The smallest possible size for anything in the universe is the Planck Length, which is 1.6 x10-35 m across.
This duly appears in the form of nonsense answers when the equations are used at the smallest distances. Physicists are therefore increasingly suspicious of points, and asking whether in fact Nature has a limit for the smallest possible object, or even whether there is a smallest possible space.
