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.
The smallest space you will likely need to consider will be one that is 12 feet in width with a maximum depth of 45-50 feet. That said, the most common unit size is 14 feet wide with mixed depths up to 40 feet and an eave height of about 16 feet.2.
