What do you need for a successful PCR reaction?
The key ingredients of a PCR reaction are Taq polymerase, primers, template DNA, and nucleotides (DNA building blocks). The ingredients are assembled in a tube, along with cofactors needed by the enzyme, and are put through repeated cycles of heating and cooling that allow DNA to be synthesized.
What is the crucial step in PCR?
Denaturation: The double-stranded DNA is heated up to 98ooC which causes the hydrogen bonds to break and the two strands get separated. Annealing: The two sets of primers are added which bind to the appropriate complementary segment of DNA strand.
What is the minimum but critical DNA sequence information needed for the successful design of a polymerase chain reaction PCR?
In order to use PCR, the exact sequence of nucleotides that flank the area of interest must be known. This is the absolute minimum data necessary before a typical PCR reaction can be used. This data is necessary for the design of PCR primers that are 5u2032-3u2032 oligonucleotides of about 20 nucleotides in length.
Which of the following statements is accurate for the PCR polymerase chain reaction?
PCR (Polymerase Chain Reaction) In this reaction, multiple copies of the gene (or DNA) of interest is synthesized in vitro using two sets of primers (small chemically synthesized oligonucleotides that are complementary to the regions of DNA) and the enzyme DNA polymerase. Hence, Statement 1 is correct.
