what are some of the advantages of pcr name 1 and explain?

PCR has a number of advantages. It is fairly simple to understand and to use, and produces results rapidly. The technique is highly sensitive with the potential to produce millions to billions of copies of a specific product for sequencing, cloning, and analysis.

The polymerase chain reaction (PCR) is used to make millions of copies of a target piece of DNA. It is an indispensable tool in modern molecular biology and has transformed scientific research and diagnostic medicine. ... In this interactive, learn about the diverse range of technologies that are possible because of PCR.

The equivalent of DNA polymerase I and DNA ligase are also unnecessary due to the absence of RNA primers and Okazaki fragments during the process of PCR. Since PCR requires very high temperatures as you will see, a typical DNA polymerase cannot be used since it will be denatured by the intense heat.

There are really a couple of advantages to the "scientific" naming system, and one disadvantage. First off, scientific naming is standardized. Each creature has only one scientific name, and each name refers to only one creature. This is of great advantage because it allows precision.

RNA primers are needed to begin replication because DNA polymerase is unable to do it alone. DNA transcription does not have the same problem because RNA polymerase is capable of initiating RNA synthesis.

PCR makes it possible to produce millions of copies of a DNA sequence in a test tube in just a few hours, even with a very small initial amount of DNA. Since its introduction, PCR has revolutionized molecular biology, and it has become an essential tool for biologists, physicians, and anyone else who works with DNA.

The process involves the use of primers, which are short strands of DNA generally about 20 nucleotides long, made in a laboratory. ... Although primers composed of RNA can be used, DNA primers are more commonly seen in PCR as they are more temperature-stable, which is important during the annealing process.

The lower amount is the better !!! Generally, with a final volume of 50 uL I use 50 - 100 ng of genomic DNA and 10 -50 ng of plasmid DNA. 30 cycles should be used in PCR - the range is 25 -35; more cycles increase the probability of aspecific products.

PCR is used in many research labs, and it also has practical applications in forensics, genetic testing, and diagnostics. For instance, PCR is used to amplify genes associated with genetic disorders from the DNA of patients (or from fetal DNA, in the case of prenatal testing).

A key difference between ELISA and PCR tests is detection limit. Typically, an ELISA-based method will have a limit of 104-106 CFU/ml, whereas a PCR method can detect in the range of 103 CFU/ml. This difference in detection limit usually means that a longer enrichment time is required for an ELISA method.

PCr can function as the major source of energy for events lasting up to about 1 minute. PCr can be activated instantly and can replenish ATP quickly enough to meet the energy demands of the fastest and most powerful sports events such as throwing and sprinting.

In the PCR you need the DNA sample, nucleotides, buffer solution and primers. The PCR is used to produce many identical DNA samples. The restriction enzymes are used for a restriction digest, where the DNA is cut into pieces. This is useful for an analysis of the DNA (I can't explain it in a sentence).

RFLP analysis is often used for DNA profiling. Real-time PCR on the other hand, utilizes heat-stable DNA polymerases to amplify minute quantities of DNA especially when more DNA template is required for further reactions/analysis.

A number of DNA viruses, RNA viruses and linear plasmids use small proteins as primers for DNA or RNA synthesis (Salas, 1991). These proteins are covalently attached to the 5′ end of the DNA or RNA genomes. ... Thus, these polymerases are structurally adapted for using either a protein or a nucleic acid as a primer.

HSV PCR is a single test that both detects the presence of HSV DNA and determines which type is present in the positive samples. There is no mechanism, therefore, for testing for HSV-1 without simultaneously testing for HSV-2.

The difference between the proportion of culture positive and PCR positive specimens for both organisms individually and collectively was significant (P < 0.001). From our study we can conclude that PCR is more accurate than bacterial culture in detection of organisms in middle ear fluid in OME and that M.
