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.
Since the lengths of each side of a triangle is also less than the sum of the lengths of the other two sides, we can say that XZ is less than 450 miles + 100 miles or 550 miles. We can conclude that XZ must be between 350 miles and 550 miles.e must find the degree measure of the other two angles of triangle ABC. Since the measure of angle A = 30 degrees, then it follows that the other two angles must be equal and add up to 150 degrees. That means they are each 75 degrees. That means the side opposite angle A (side BC) is the smallest side.
