In qualitative PCR specific DNA fragment is detected while in quantitative PCR our target DNA sequence not only is detected but its amount is determined (after reaction we can calculate the amount of DNA we had in our sample)

What is the defference between Real-time PCR and reverse transcriptase PCR?

Real-time PCR is a technique used for quantifying DNA in real-time during the PCR process, while reverse transcriptase PCR (RT-PCR) is used to detect RNA by first converting it to complementary DNA (cDNA) using reverse transcriptase enzyme before proceeding with PCR amplification. Real-time PCR allows for monitoring the amplification process as it occurs, while RT-PCR is specifically used for analyzing RNA levels.


What is the enzyme that synthesized DNA used in PCR that distinguishes it from the equivalent enzyme that carry out the same function in our cells or those of most bacteria?

The enzyme used in PCR to synthesize DNA is called DNA polymerase. The key difference is that the DNA polymerase used in PCR, such as Taq polymerase, is derived from a thermophilic bacterium called Thermus aquaticus and can withstand the high temperatures used in the PCR cycling process. This distinguishes it from the equivalent enzyme in our cells or most bacteria, which would be denatured by the high temperatures of PCR.


In a pcr reaction of DNA are first separated by?

In a PCR reaction, the DNA strands are first separated by heating the sample to a high temperature (usually around 95°C), which breaks the hydrogen bonds between the two strands and results in denaturation. This step is necessary to allow the primers to bind to their complementary sequences during the subsequent steps of the PCR process.


How you calculate nested pcr product size?

To calculate the size of the nested PCR product, you would first determine the size of the first PCR product by adding the sizes of the primers and the DNA template. Then use the first PCR product size as the template size for the second PCR reaction, adding the sizes of the second set of primers to estimate the final nested PCR product size. Keep in mind that any additional flanking regions may also contribute to the final product size.


What is pcr case?

A PCR case typically refers to a case in which a polymerase chain reaction (PCR) test is used to detect the presence of a specific genetic material, such as a virus or bacteria. PCR testing is a common method for diagnosing infectious diseases like COVID-19.

Is reverse-transcription polymerase chain reaction quantitative or qualitative?

Certainly rt-PCR is qualitative and can also theoretically be quantitative. Anneal the RNA to get a 1:1 RNA to DNA copy, then proceed with quantitative PCR.

What is the difference between touch down and gradient PCR?

Touch-down PCR is a method where the annealing temperature decreases in each cycle to increase specificity, while gradient PCR involves testing a range of annealing temperatures in a single experiment to determine the optimal temperature for PCR amplification. Touch-down PCR is useful for reducing nonspecific amplification, while gradient PCR is helpful for identifying the optimal annealing temperature for a specific primer pair.


What are the differences between conventional pcr andreal time pcr?

PCR allows amplification of DNA for a specific gene, after too many cycles of PCR the result will reach saturation, basically meaning all of the DNA has been amplified. Conventional PCR will basically tell you whether or not a gene is expressed in your sample. This can be done semi-quantitavely if the PCR is performed for a low number of cycles, ie it will tell you whether one sample expresses more of your gene of interest than another sample. The results are seen by separating the PCR products by agarose gel/ethidium bromide electrophoresis. Real-time PCR will record exactly what cycle of PCR a detectable level of amplified product became detectable, giving a far more accurately quantifiable estimation of gene expression.

Does 50ul PCR product work better than 25ul PCR product?

The volume of PCR product used does not necessarily determine its effectiveness. The critical factors that affect PCR performance include the quality and concentration of the DNA template, presence of inhibitors, primer design, and PCR conditions. It is best to optimize these parameters for successful PCR amplification rather than focusing solely on the volume of PCR product.


Why do two possible PCR products differ by 300 base pairs?

The difference in size between two possible PCR products could be due to variations in the regions flanked by the primers used in the reaction. If one primer binds closer to the target DNA region than the other primer, the distance between the primers and the resulting PCR product could be shorter or longer. Additionally, differences in DNA sequence, such as insertions, deletions, or mutations within the target region, can also lead to variations in PCR product sizes.


What is pcr and types of pcr?

PCR (polymerase chain reaction) is a molecular biology technique used to amplify a specific segment of DNA. There are various types of PCR, including quantitative PCR (qPCR) for quantification of DNA, reverse transcription PCR (RT-PCR) to amplify RNA, nested PCR for increased specificity, and digital PCR for absolute quantification of nucleic acids.
