PPT-Unit 2: The Genome Chapter 6 - Polymerase Chain Reaction

Figure 601 Polymerase Chain Reaction PCR During PCR two primers anneal to complementary sequences at either end of a target sequence on a piece of denatured sample DNA DNA polymerase synthesizes a complementary strand of DNA from the primers resulting in two new strands of DNA In further cycles the newly made DNA molecules are denatured primers are annealed and DNA polymerase copies the target regions resulting in multiple copies of the original target sequence.

PCR produces billions of copies of a specific piece of DNA from trace amounts of starting material. (i.e. blood, skin cells, bone). Allows scientists to isolate pure quantities of specific DNA sequences. By: Savana Canary and Kathryn Wolfe. What is it?. Polymerase Chain. Reaction (PCR) is when . you amplify the number. of copies of a specific. region of DNA, in order . to produce enough DNA. it be adequately tested..

Those based solely on their unique sequences are known as sequence tagged sites (STS). These unique sequences may be amplified by PCR and mapped relative to each other. In practice, each STS is defined by a pair of specific PCR primers at its ends that generate a PCR fragment of defined length.. Johnson DJ, Ostlund EN, Pedersen DD, Schmitt BJ.
