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.
At its closest it is 3,427,897,856 miles and its furtherest it is 8,986,854,136 miles from the sun. Now at the scale of the earth being a foot wide. At this scale Earth will be 2.2 miles from the sun, and Eris would be 82 miles to 215 miles from the sun. Eris is 1,645 miles wide. It has a moon called Dysnomia it is thought to be 62 miles wide to about 155 miles wide.
