What is the goal of PCR?
Homework Answers
PCR stands for Polymerase Chain Reaction. PCR is a biological process in which millions of copies or clones of a particular DNA are made in very little time. The main goal of PCR is the treatment of genetic patients, the study of the genetic development of humans, the discovery of new viruses and bacteria, etc. Today, PCR has become an important tool in biological laboratories.

What is the difference between regular PCR and RT-PCR? In RT-PCR you can measure the amount of DNA copied by adding a fluorescent dye. The fluorescence increases as the desired sequence is amplified. O In PCR, there is a higher chance of contamination with undesired samples because primers are less specific than in RT-PCR In RT-PCR, new sequences can be added each cycle which makes the process more dynamic and efficient. In PCR, the temperatures vary more than in RT-PCR...

EXPLAIN each answer thoroughly. There are two common goals when using PCR to amplify DNA. A. Make lots of copies of a specific DNA sequence to use in cloning (preparative PCR) B. Detect the presence or relative amount of a specific gene under varying conditions (analytical PCR) *Remember: PCR is very similiar to DNA replication, but uses a DNA polymerase to amplify only specific parts of DNA sequence based on the sequence of the primers. 3. For which goal (A...

Some of the PCR techniques for DNA amplification are: Regular PCR Hot start PCR High-Fidelity PCR Immuno PCR. Real-time PCR ------------------------------------ 2. The following information about Taq DNA polymerase is/are correct. Taq DNA polymerase was discovered by Kary Mullis in 1983. The entire Taq DNA polymerase reaction (PCR) technique was bought by Perkin Elmer in the range of $120 million. Kary Mullis received a Nobel prize in 1993 for discovering Taq DNA polymerase. Taq DNA polymerase was isolated from Thermus aquaticus....

5) p points) Temperature regulation is critical while preforming PCR. What could resuit IT the PCR reaction is not cooled to 42°C -65°C before the extension step? Why would this occur (2 points) If you start with one copy of a single gene of interest and perform PCR on that sequence, how many copies of the gene would you have after 10 cycles? Explain your reasoning.
